You guys seem to have an interesting board over here I think I am going to have to start spending some of my time here as well.

As far as 95'* chip yes we are experiencing some issues with his idle and decel, no doubt the aftermarket cam is wreaking havoc with the decel fuel cutoff tables in the chip. No problem I can fix that. Like I told 95 in the many PM'*, I strive to attain the best possible customer satisfaction and service, period. I will work with him until his chip meets his expectations. All of my custom chips come with a 1-year warranty.

As far as what experience do I have with tuning, dynos, etc well I have an Associates Degree in High Performance Automotive and I did do dyno work while in college, which included ECM tuning for max performance. But that is just part of the story. Most of the custom tuners out there today just tune for WOT and really don't spend too much time on part throttle drivability. While this is fine for a race car, like you I drive all of my cars on the street daily and it has to be tame as well as fast.

So far all I can do is most GM applications up to and including 1995. Yes, I can tune ALL 88-95 3800 systems, SC or N/A. I am even running a 95 Bonne PCM on my 3800 Series II Turbo and have done many chips for the 96-up L67 using the 95 PCM in Fieros.

As far as the superchips and their claims there is no way a computer chip for a 4T60-E equipped car is going to raise trans line pressure. That is a function of the vacuum modulator and the PCM has no control over it. Only the 4T65-E'* used in the 97-up cars had PCM-controlled line pressure. However, you can get an adjustible modulator and bump up line pressure that way.

In any event I would be happy to help anyone who might be interested. Remember, I don't only do chips, I also do engine swaps, custom builds, fabricating, and turbocharging so if you have any questions please feel free to ask.

-Ryan

Darth,

Since you're here, I'll put you on the spot Ever walk on coals before? But before I do, I'll tell you we've been using your website for reference material for quite some time. Nice setup over there.

Awhile back, we had a lightly modded 95 SSEi owning member that claimed you were going to burn a chip with redline shifts for him. My understanding from him was that you had already agreed to do so. Do you recall this (maybe in the last 2 months?) and what are your thoughts on the subject? I'm betting from reading your resume, that you actually might have a totally different story.

Anyway, after we get THAT out of the way welcome to the club, and PM and Administrator sometime soon for Vendor expectations and rules for the Bonneville Club.

LOL I walk on coals quite often now that I think about it. To be honest with you I have done so many chips it is hard to recall specifically doing one for someone over a couple of months ago. If you could supply an email address of the member I could track it down in my records but as of now I don't recall doing a chip involving "redline shifts".

Now as far as my capability, I can do almost anything with the Bonneville computers, some systems like the 94-95, I can do more with than the earlier 92-93 and 88-91 systems.

I'm not going to point the member out in public, but I can tell you our concern was that not only would this damage the car over time, but it'* ridiculous to program a chip to shift so far out of the hp/tq curves. This would actually end up being detrimental to performance and reliability. Again, I don't know if he actually talked to you and understood you WOULD do this, but that'* the impression we got.

There have been a handful of cases where our members have thought that redline shifts would be beneficial. Dare I say that this is the 'ricer mentality', and is understandable that people would have this misunderstanding, considering all the bad information running rampant in the import tuner market today.

Keep in mind, I'm not picking on you (or him), but can you explain your process for determining shift points on a modified car? Without the ability to actually put that car on a dyno? There are varying views on this here, and your explanation could go a LONG way, and perhaps answer some unanswered questions for us.

I understand where you are coming from concerning the privacy standpoint, but I am not asking you to point anyone out to me in public, a simple PM would have sufficed.

All I can tell you is I try to do everything the customer asks. If I see a request that doesn't look right or is questionable to me, I will email the person and warn them or have them clarify what they want done. But the bottom line is if someone is firm on their decision after I have provided them with my advice/warnings, I will ultimately do what the customer wants. I have a nice legal disclaimer that accompanies all of my custom chips that basically says I am not responsible for damages, etc. This same arguement could be made against any company that raises the top speed limiter on the stock chip and someone went out and had a tire failure due to excessive speed. I can't be held responsible for someone else'* choices.

Now as far as my opinion on the whole shift point thing is well it depends on your mods. Certainly most stock engines may not benefit from extended shift points but with just light mods they can. In cases like with 95'* car, he has an aftermarket cam and in his case if his shift points were not rasied he would probably lose performance because when the trans shifts at the stock point the RPM'* would drop down below his new powerband and the engine would effectively bog. But as far as a stock motor again it depends on the mods and everybody'* car is different. I will give my recommendations but ultimately the choice is up to the customer. Dyno work is another matter. Dyno pulls are done at WOT with no shifts so a dyno is not going to necessarily tell you whether or not holding out the shift points is going to help. Yes, it may tell you where your power band begins or ends, but those numbers don't always translate into gains/losses in the 1/4 mile. Ultimately the best tune is going to come from data collected from a 1/4 mile run, not a dyno pull. This brings up another interesting point I would like to touch on briefly. Not all chassis dynos are the same, in fact there was a lot of talk not too long ago about the descrepencies between two dyno shops, using the same hardware! From what I gathered it sounds like for the most part a chassis dyno is only going to be as accurate as a G-tech, depending on the experience and training of the people setting it up and the calibration of the equipment. Not to slam all chassis dynos but I just want you to be aware that you can't always rely on those numbers. On the other hand 1/4 mile timing equipment doesn't lie and the numbers can't be as easily fudged. The nice thing is the 1/4 mile time will tell you how your car performed thru all the trans shifts, shift points, etc, not just a dyno pull in 3rd gear.

Now as far as shift points I can tell you that the L36 engine is unique in that it likes to be run out a little farther than earlier 3800'* but its stock shift points are still pretty low, somewhere around 5600rpm I think. I did a L36 / 4T60-E swap into a Fiero not to long ago and the engine is bone stock except for 2.5" exhaust and K&N filter and it likes to shift at about 6000 rpm for maximum performance. But on the other hand my experience with the L motor (TPI 3800 L27), because of its horrible intake design it'* powerband is basically dead at 5000 rpm. Taking it higher than the stock shift points probably wouldn't increase performance at all and could possibly hurt performance to some degree. However, again if a customer comes to me and insists on having higher shift points I will ultimately do what the customer asks, but I will offer my advice/warnings concerning the matter just to make them aware.

Darth or Ryan questioned about my 1100 idle.
I know it'* kinda high but that'* what i want.
