Procharger tuning problems on 99 GT

[Felonious]

I picked up a Procharger P-1SC May before last. I bought all the goodies that ATI recomended so that the setup would work just right. I took it to the local speed shop in Seattle (Lake City area) and had them do the installation. On their recommendation I went with a JMS chip in place of the chip provided by ATI as they said the ATI chips were a little quirky. After 6 weeks and 6 reburns of said chip I got the car back running kinda OK. It had plenty of power (376 hp at the rear wheel) but was still running rich and very difficult to drive if it wasn't WOT. At that point, the speed shop said they didn't know what else to do for the chip issue. Then the chip popped. This chip came with 4 programs on it and a dip switch to change them up. One of the programs is a safty program that rev limits the engine to 2500 rpm. Well, that is all that worked. I sent the chip directly back to source reseller in Vancouver Wa. to have it reflashed and it was barely drivable after that. After a call to ATI and begging over the phone, they reluctantly sent me a Diablo chip with their program for this setup. The car is now very mild mannered but bucks like crazy when it get's up to 3500 rpm (a product of running pig rich from what I understand). On ATI's recomendation, I repositions the MAF and regapped the plugs. Still no luck. I have called several other speed shops in the Seattle area to see if they can tune the car - but so far none of them have the software and supporting equipment to do so under one roof. Anyone out there know where I can go to get a competent tune for my Pony?

The set up is as follows: ATI Procharger P-1SC 10 lbs blower, 3 core intercooler, 42 lbs injectors, 70 mm TB, 1999 Ford Lightnigh MAF, stock H pipe, Flowmaster CAT backs and Denso Iridium plugs.

Any help would be greatly appreciated!

Thanks guys for the feedback!

I have been involved in tuning several vehicles with chips and have found mail order chips do not work as well as custrom burned chips. Mail order chips are a general tune that works on most cars. We have built several cars with the exact same combo and tried to use the same chip tune with varied sucess. Due to changes in the chip world as of late some hardware is no longer supported. JMS, Ford Chip, and Superchips have merged into the new SCT chip. Mike Wesley who developed the auto logic chip used by these companies now works for Diablo Sport and the Autologic chip is no longer supported. What ever chip you decide to use or who ever you have tune it my recomendation is to have the chip burned on site and not through the mail. We have had much greater luck tuning being able to write the program with the vehicle on site at the chassis dyno. Its worth the drive to have it done right. Call Blue Oval Performance, he can get it tuned right with the vehicle on site.

That, or do as I did, get the software/hardware to do your own tuning. SCT is offering a racer package that comes with a base tune you can modify... It takes some studying and the learning curve can be steep, but there's no replacement for being able to make modifications yourself.... You have access to almost every parameter a tuner would and you're not tied into mail order or a 160 mile drive for a tune.

How much was that? And is it a chip or a piggy back system?

It's costs a bit, $795 for either the flasher or 4 position chip + SCT Advantage software.

For that price you get the flasher or chip, software, support and a baseline tune for your modifications to work from and the stock values for your PCM.

Take a looks at www.modulardepot.com - it's the only place you can get it at this point. They have a forum setup specifically for those using the software and the SCT guys frequent it to answer questions. They also post value files for different modifications on the forum - injectors, shared files, etc.

There are a couple other tools you may want if you decide to tune on your own. A wideband a/f meter will definitely help and some kind of code scanner/datalogging setup. I use the autoxray scanner.

Hope it helps,

Are they doing custom tuning now? Last time I was there they were only doing the basic Diablo tuning - which means run it on the dyno and then either look for a file that fits or wait for Diablo to write a file.

I know they were going to try the Revolution software, but I didn't know they decided to do it.
