peter farrell ECU
 

hey I need some help. I have a 94 r2 and found the PF ecu hardwired to my rx7 when I bought it. Well I lose the engine and now currently having it built. I was wondering if any of you guys have tuned the ECU before its basicly a piggy back to the stock ECU. Dont know whether to remove it and use the APEX FC or stick with my set up and try to tune it.

Depends on your mods honestly. What do you have done?

The PFS ECU isn't called the purple motor eater for no reason. It's old technology.....I would recommend the Power FC. What mods do you have on your fd?

Apexi PFC is the better set up.

I have the PFS and it is decent for slight mods. you can adjust the overall fuel map increments at low, medium, high, and wot loads at 2200, 4000, 6000, and 7800 rpms. It aslo has timing adjustments at these rpms, cold start values, boost control, vent control(for stock twins),NOS injection, and cold start values, and a few others. It has three diff settings on a knob labeled 1 2 3 for seperate settings that you have preset and saved. For real time tuning, it has 02 values(narrowband), total timing, rpm, boost, and NOS. for the cheap price it isn't to bad if you have plans for only limited mods and you don't have plans for bigger and better in mind. However the downsides are that the software that it used to be sold with is no longer made and hardly anyone uses this anymore cuz of limited info and its limited capability compared to the PFC, which has tons of info, software, upgrades and its wide range of tuning capabilities. The general consensus is to go with the PFC. Hope this helps.

Do yourself a favor. Throw the purple motor eater in the trash. Its junk. You'll be installing another engine if you keep it on there. Get a Power FC asap.

The only thing I use the purple box for is to get customers cars, mostly stock ,to pass smog test , Use the Power FC to run a modifed car .
