Kevin Wyum told you what you need to know. I have had the purple on my car since mid 1990s & i run 11.6 with a cat, stock sequential twins.

There is no substitute for tuning though & as Kevin said, boost control is risky if you run a midpipe. With a high flow cat, I get pretty steady 17-18 on setting 3 with race fuel. Peter tuned it for me on the dyno though.

The maps Farrell sent out with the original were real rich. Just don't run a midpipe and you will be fine. And only use setting 3 with RACE FUEL.

I had the "pink 9" as well. Better that you tune it with a wide-band on the street than on a dyno. Dyno's leave you running lean. I've already been there, done that. Your PMC should be adequate - it's the stock wastegate being overwhelmed by the upgrades. They need to be bigger; needs to be hogged out.

Yeah, EFI system told me that they were no longer supporting the PFS computer. No updates or spare parts! My keypad went bad and there's no replacement.

Since they no longer are supporting it, I've decided to copy their Proms and burn it. That way I can use the InterACQ without the keypad and just a laptop.

So far I found a 2 Eproms:

27c256 and 28c64. All the other active components are the same. The 27c256 is placed in a removable socket. Not sure which one stores the user setting and which one stores the controller software.

Well, Well, Well, where do I begin...Let me start by listing my upgrades.

PFs down pipe
cold plugs B9`s leading, B10`s trailing
PFs intercooler and cold Air Box
Walbro High Pressure pump
Cat back exhaust.

I installed the computer and drove the car...Cannot really tell the difference in comparison to the stock computer....So i decided to put some load on the motor.
after driving it for about 3 miles.

I ran the car on the low setting and notice that the boost is still spiking, 13psi to be exact.
so i set it on the med. setting and still 13-14 boost. car feels o.k. I notice that my Exhaust Gas Temp is about 1400 degree`s

My experience with rotaries using Haltech/Microtech leads me to believe that the motor is still running lean...I was hoping that under load the motor would have given reading of 1250 degree`s the max...since it was reprogramed...Hope that Peter Farrell and his crew hasn`t given me a six for a nine.

I`ll get it on the dyno tomorrow and see what the stoich readings are and take it from there...In put is definately appreciated.

Steve Cirian's web site has some maps for the purple
computer.
They were from Dale Black's dyno run with a full
exhaust and intake, SM intercooler.

Thanks for the link...However, I drove the car today and it feels pretty good through the transitions....seems to be really smoooooooth, Just what i have been looking for.

But I`m now in need of a keypad, just in case I need to make any changes on my own. If anyone has one for sale please give me a call 561 716 2678 or e-mail me at:synco357@aol.com

Thanks again to everyone for their advise.

Sincerely,

Andre Sinclair
