Hi guy's and girls, hoping you can help. I have a 91 Z28 TPI with a 383, vortech blower, and lots of other goodies. I am trying to find a company that can build me a custom chip to tune this baby in. I've checked with various dealers like Diablo, Hypertech, SuperChips and all say that they don't deal with this year model. So can anyone point me in the right direction, or tell me which chips they use?

I have contacted Jet Performance and they say they can burn them, but I'm trying to get more options, and more information,

Thanks

 

best bet would to have it dyno tuned. You could also get into prom burning and do it yourself, but there is some equipment and a few tools you need to buy first. It is a good investment though.

 

It was my understanding with the ecm in the 3rd gens prom burning was not possible, only chipping. Is this not true?

 

Yeah, honestly your best bet would be to get into doing it yourself. Most people are going to say that because the companies that make the chips aren't really that good. They are OK but not great. Also, with the amount of money your going to spend on the chip, you can purchase all the equipment and be burning chips before you even get a response about your "custom" chip. Also, all thirdgen ECM chips can be burned.

Hope that puts ya in the right direction and good luck.

This will get you by until you learn to burn your own.

 

what you need to know about prom burning and how to do it yourself

ps: word of suggestion if you get a laptop to do this, make sure it has a serial port or dont bother.

 

B4, I plan on using my laptop for it, would make it so much easier. Right now I'm still just scanning articles trying to figure stuff out.

 

yeah thats the hard part
working on it myself
the good news is that the stuff is not expensive and alot of the source is open (free programs)

people sell scanning cables and burning stuff all the time here in our classifieds as well as on ebay

You are fighting an uphill battle if you actually do mail out for a "custom" chip.

I have seen the programming of so called "custom" chips. They all look real damn similair. Its really more like a cookie cutter program that they mail to your door with your name on it, if your vocabulry is weak you can call that custom but in reality its more of a sham.

The mail order people dont want to help you, they just want your money.

There are numerous threads on these boards where people do nothing but spell out bad situations they found themselves in after dealing with a custom tuner. You will however find a decent amount of success with custom tuners, HOWEVER, this is most often when the tuner mailed the cookie cutter program to an owner who had an NA motor and was running a car that employed a MAF.

Tuning a Speed Density blower car through the mail will be a failure. Tuning a Speed Density blower car on dyno with the tuner may get you farther but it will be very expensive. But at the end of the day, the computer system in your car is not designed to run a blower setup, you will never get your moneys worth.

Post this same question on the DIY PROM board and the DFI/ECM board.

Whatever you do, do not ignore the facts and do not go into denial about the situation.

 

Ominus: The only real mail order chip I considered would be from TPIS. But, using their software that you can rent, log all the data from various things like cold start, WOT, etc, etc. Then have them burn a chip on the actual data from the computer, along with my dyno tests.

But at the same time I realize the $8D that I'm currently using doesn't have anything to do with blowers like the $58. That's something I would have to ask them if they would change. If not, or they gave me the runaround it'd be out the door for me, and back to the forums.

I did however move over to the DIY ECM board and am seriously looking into doing it myself. I just have to make myself comfortable with knowledge before I try and burn my own chips.

Denial? How could I be in denial if I'm asking questions and trying to learn? Wouldn't that be contradictory?

Thanks for the input!

 

Fastchip - He did an awesome job on the custom chip I bought from him several years ago, before buring your own became popular. It's dead-on, I've verified it with scan data, dyno runs and WB02.

 

I briefly talked with the guy from fastchip on the phone. He did impress me, however I forgot to ask about the mask change and stuff. That's one of my biggest concerns.

As I read info in the DIYECM forums I now know it's a neccesicty for my ecm to have the $58 mask and not the $8D, so as I stated previously, unless they can do that, there's no deal.

However if they will I was thinking of going ahead and getting it done while I learn how to burn my own. I plan on doing it myself in the future, but the fact remains I need a chip now. And I won't just jump into burning myself and risk ruining stuff.

 

Some clarification my friend!

That was not a shot at you, there are pleanty of other lurkers here reading this stuff, it is for everyone that might be confused.

Upon further examination and psychoanalysis of people who approach their propblems without an open mind and true desire to have the correct answer in hand, it is typical for them to go into denial and grasp for a simple solution with questionable results while ignoring the facts of the circumstance and only really dealing with the problems of that choice when a catastrophic event occurs to open their eyes.

I hope that we are on the same page now

 

Sure fastchip knows his stuff. However he will not be able to precalculate or predict the VE needs of your motor. Just aint gonna happen. Maybe get it up on his dyno with the mask conversion and you will be able to get somewhere, maybe not though. Either way, your still gonna pay for it.

Just because McDonalds sells cheeseburgers doesnt mean that the product is any good.

 

I didn't think that was a shot at me, heh. I'm an irritable person when people bitch at me, I would've been yelling and screaming and my post probably would've been deleted if I thought you were talking a shot at me. heh

No worries, I was just making a joking type of point

VE? Unfamiliar with that abbv. Aye, I hate McDonalds :P Accept when I need a cheap .99$ double cheesburger...Only ketchup though :P

Isn't the mask switch a software switch within the prom? That's the one thing I'm still confused about and can't find info on. I found tons of info on switching to the 749 ecm out of syclone's and such, but nothing on simply switching the masks.

I've asked in the DIYECM forum but I keep getting directed to the syclone articles for switching to the 749, instead of just the mask, or I get told "You've already been told were"

Thanks.

Thanks, dropped him a line to chat.

 

your best bet is to find someone whom can work with the car on the spot.....doing mail order should be your absolute last resort.

 

Excellent Meffie, Glad I could help. I don't think you'll be dissapointed, my brother in law knows him personally and says he is really good, been doing it for quite sometime
