I little information on my Northstar Tuning

[caleditor]

Does anyone her drive WOT and then brake and then back WOT?
If that's the case I will send you a tuned PCM for free. You will not be able to drive it on the street because I will build you a dyno tune that will throw down a huge increase at 6000, but I will pull out everything below 3000.

I can tune a car to make a lot more power from 1500 to 5000 and a little over stock from 500o to 7000 or I can tune a car to make say 40 hp more at 6000.

Think about that

[Randy T.]

Yes, I do that all the time. I will take you up on that offer. I like to clean the carbon out and test my brakes, too. I do that a few or more times a week. I can't keep anything in the seats or it flies off and gets damaged.

I can swap a pcm very quick, too, so I would not take it on the streets. There is a 1/4 mile track close, too, but they don't open until the weather gets warmer. So it would be a couple months before I could take it to the track.

[Randy T.]

You can send it to my work or home, would prefer my work, I am there more. If you say I can't drive it on the street it will take a while to get video out at the track, I don't know if there are any dynos around here, it would be easy to do a before and after with the pcm swap.

I may have found one, we could get this taken care of pretty easy. I don't know what it cost, and I don't have much spare cash, but I will check it out. Be nice to get gator there with his 4.6, too. lol

[Randy T.]

2 Before & 2 After pulls $125.00

Not too much, but more than I have to spare, I could always sell a few parts to cover it, get it figured out one way or another.

No problem I will make up a special tune that will not be able to be driven on the street and only make more power over 5000

I will do my best to kill the engine off below 2000. As a mater of fact I can make it run on 4 cylinders below 2000.
I will put in full abuse mode below 2000 and then have the abuse mode disable above 2000. Boy it will be the crappiest tune that I has ever sent out, but I will tune the WOT settings to pickup about 20%

This is the reason we mainly sell street tunes. We spend days driving the cars on the street working out all of the bugs. WOT tunes are a basic tune that is very easy to do. Making the car have more power lower in the RPM range and better drivabilty is key to having happy customers.

Sooooo....it's settled then, right?

What you are saying, is that you are willing and ready to send out a tuned PCM to Randy at the above address? Because that is what I gather from your above response.

If your PCM does what you claim, I promise you that I will personally recommend you to every single person I know. If you can tune an AUrora PCM, I imagine you could tune quite a few others.

Just for curiosity sake, what make and models are you able to tune?

[wireless]

Agreed. I'm willing to throw money your way =)

[caleditor]

That won't be an issue.

[caleditor]

Your PCM is on its way to Tom in Rockford with 7 other for Tom to repair. When Tom gets it repaired I will give him a bin file to load and send out to You. I will make sure you get the one that will not run except WOT. I sent Tom 3 96 to 99 PCM's and one of ther others will be goind out to a paying customer

[lanceslambos]

i don't understand. you tune pcms and then the car isn't street legal? what are you talking about? this is starting to sound like those internet mpg increasing gimmicks ( +100 hp, +50 mpg from a chip ) you tune the pcm and it's only good for wot all the time? that's pretty much a waste don't you think? also if your tuning these then why do you have to send it to someone else like Tom? why are you placing yourself as the middleman when westers garage, etc. supposedly uses your tune? the more this thread goes on, the least sense it makes. why would anyone want their aurora to run in limp mode unless they have the pedal to the metal?

Say you have a set of long tube headers on a Camaro. You have removed the cats. If the car is a track only car I would turn off the P0420 & P0430 DTC's so you won't have a check engine

Tom aka programmer@pcmcalibrators is an engineer technician that worked for Motorola for over 14 years. He is still in the industry. Tom is my hardware tech. On these old Northstar PCM's we pull the memory chips off of the PCM board and program the chip on the bench in a chip burner. I own the equipment and Tom uses it up in Rockford. If you read the thread from the beginning you would understand that’s how we tune the old Northstar PCM’s. Also if you go to our site you will see Tom’s contact information.
This thread was supposed to be more of a DYI thread and it got way off track.

[caleditor]

The Tune that I am sending out to the none paying Randy will be made so that the car will not run very well except WOT. See he wants to dyno the car. WOT pull are what you do on a Dyno. If you look at the calibrations that is a very very very small part of the calibration.

I will set the Timing and the AFR to be correct at WOT from 3000 to 7000 and everything else will be JUNK.

Does that make sense?

[caleditor]

Hey Lance you should have come see me in Milwaukee when I was at the Caddy dealer.

Today I am working on a
1966 427 Vette -- Full under carriage rebuild
1964 327 Vette – Frame on at this time rebuild of the car
1989 Vette – Gauge Cluster rebuild
Next in line is a 1999 Vette that the guy wants Twin Turbo’s installed.

Here's how it's going (to my understanding).

He is sending Randy a PCM to PROVE that he can in fact tune it. He is sending it with a very specific calibration to prove that he can do what he does.

I would also assume that he is sending it because Randy isn't paying for it, so he's sending him a PCM that isn't very drive-able. Just my point of view though.

Felling like I'm about to witness history!... A tuned Aurora! ;D

Can''t wait to see results that Randy posts!

Moment of truth!

[Randy T.]

I will have a different address, I am moving and switching jobs, will post the address soon. And if it matters, my cat is hallow.

[caleditor]

This one is on the slow truck.
I sent another smaller box with only 1 PCM, but it had 3 empty cases at the same time and Tom has it already
UPS

I sent the Shelby Book out one day before this box and shelbyracer got that a few days back

I've been considering the cost of the dyno vs the track. I can go to the 1/4 mile track a lot cheaper, so that may have to be where I test it.

This is the reason we mainly sell street tunes. We spend days driving the cars on the street working out all of the bugs. WOT tunes are a basic tune that is very easy to do. Making the car have more power lower in the RPM range and better drivabilty is key to having happy customers.

Although I am willing to use my car for this WOT tune, it still would not prove that a street tune is possible. It sounds like there is a big difference between the 2. The WOT tune sounds similar to disabling the torque management. I am not saying they are the same at all, because I don't know, I am wondering the difference. The question here is if you can make a pcm that has more power, higher rpms, and better gas mileage.

I am willing to use my car, but it seems like the point has gone a different direction.

And there is no reason to dis me because I am the no paying Randy, as you say. I volunteered my car to help you out, and I offered 2 pcms for one, but you did not take the offer.

When we tune a car we tune it for the street. We can do this on a load bearing dyno or by driving it on the street. Like I stated WOT power is not to difficult to nail down. You are only tuning the car when the MAP sensor is reading low vacuum.
We may spend 2 hours on the street or drivability side of the tune and a 1/2 hour on the WOT part.


By Greg Banish

Having tuned lots of cars over the years, I've had the opportunity to do so many different ways. When I first started, my only choice was to drive the car on the street and make an attempt watch the wideband in between glimpses at lane lines, traffic and pedestrians in some cases. While this worked great for confirming the "real world" performance of the vehicles I was testing, the conditions (and safety) were less than ideal.

Enter the chassis dynamometer, that wonderful piece of equipment that every tuning shop must have these days to be "state of the art." The chassis dyno allows for easy recording of actual WOT power and usually incorporates wideband air/fuel, engine speed, and a host of other measurements into the data array for the calibrator. The ability to record and later look back upon the data makes WOT tuning a snap once the tuner is no longer preoccupied with the prospect of jail time or worse resulting from his testing.

Today's performance enthusiasts are becoming even savvier though. They want good horsepower and street manners out of their cars. Luckily, most EFI systems have the capability to deliver this IF they are properly calibrated. The real trick is to build not just a wide open throttle characteristic of the engine, but an entire map of engine performance accurately. This means that at any given speed and load point for the engine, the ECU must know how to properly control things.

Building this map for an engine is a lot like driving from Detroit to St. Louis. Along the way, we might need to stop in Chicago or Indianapolis (even if it's just to top off the tank!) before reaching our final destination. Without a road map, this journey is more difficult and we might even get lost. But if we read a map that shows us exactly where to turn and how far it will be until the next landmark, our travels are much smoother.

EFI Engines operate the same way. They use maps to tell them where to go on their way to WOT or redline. The more accurate these maps are, the smoother the journey.

So where does the dynamometer come in? A load bearing dyno gives the calibrator the ability to hold the engine at one location while he refines the map of the surrounding area. Inertia only dynamometers freely accelerate as the engine makes more power. This makes it difficult to hold the engine steady at all the necessary map locations and build a detailed map. Load bearing dynos have the ability to hold the engine steadily in a much wider range or map locations in order to properly tune these areas. The more accurate these measurements can be at each point, the smoother the engine will run. So a dynamometer that can allow the tuner to make accurate measurements at each individual point on the map gives him the potential to make the engine run smoother in these areas as well. Keep in mind that this applies not only to fuel delivery, but the spark map as well. Finding MBT timing at part throttle requires instantaneous torque feedback at steady state that can only be done with a properly load controlled and instrumented dynamometer.

The added benefit to a load bearing dynamometer is that when it comes time to test dynamic conditions, the rate at which the engine sweeps across the RPM range can be adjusted to match exactly what happens in the real world. This means that the amount of time it takes to complete a run is the same between the track and the dyno. We have a better idea of just how much heat and load the engine will see on the street or track. In today's world of handheld flash tuning devices and "canned" tunes designed to fit a wide array of cars, testing under these real world conditions can make difference between "That should have been fine, I don't know why it broke at the track," and "Everything performed just like we expected" when the car comes off the dyno.

[caleditor]

A load bearing dyno isn't the cheap dyno and most shops do not have them.

Low tps % equals mpg
High tps % equals gpm

That is my point on WOT runs

Scanware like HPTuners has a built in dyno. It is perfect, but you can have a measurment of HP increase

My point is most good tunes are street tunes and yes they have more hP, but the WOT dyno tunes are just that WOT

[Aurora40]

None of our cars have major modifications like forced induction, radical cams, etc. Why would you need to mess with the factory tune for part throttle? GM spends about a year on this, and other than small things like fan turn on points and such, I don't think too many people have a complaint about part-throttle driveability from the factory.

I don't get the point of a crap tune either. To show you can change parameters doesn't mean you can tune in a way anyone cares about. You could change all the lookup tables to random values. I guess that means you "tuned" it, but no one is gonna pay for that.

Grasshopper you have much to learn

Hey do you have E10% or pure gas? If you have E10 you should have an E10 tune. If not it is like running about 15.3 to 1 on gas

This was not a thread to sell tunes. I was going to offer up help so others could tune.

I don't have a complaint about part-throttle driveability, however, if it can be improved upon I would definitely enjoy that.

Also, the majority of people are doubting that he can even tune an Aurora. It seems to me like that is what is being proved here, that he can simply change it.

Let me know when you are about to send it, at that point I will let you know what address to use. Unless you sent it to my shop already, I will be there for another week.

According to the tracking # he posted above, it has already been delivered.
