Overseas fuel tuning ?? Similar specs anyone ??
THIS IS ALSO UNDER POWER FC FORUM, I THOUGH I CAN GET SOME GOOD ADVICES HERE TOO... SORRY FOR REPEATING...
Guys,
My short story, I just got an Apexi SAFC2 under my shop advice, they said have no experience on PFC or rotaries, but a lot of Dyno tuning experiences on WRX or EVO´s with apexis piggyback.
Well, I did it, and now that is on the way to Chile I found out on the forum is a bad idea to use it on my 94´FD. It just doesn´t work. Am gonna have to sell it once it gets here.
So, I can get a PFC but I have to assume am gonna have very poor tuning capabilities with local shops. There are a couple of Rotaries experts, but they have never dealed with power FC.
Is it possible to get a Pre-Tuned PFC from someone ?? If I provide my specs can I get something very close to what I need ?? So the shop doesn´t have to set it up from the ground ??
Or is it better to get an used and already chipped ECU to someone else specs ??
My specs are very basic but I just want to be on the safe side.
94´JDM FD (65K Miles)
Stock Turbos - Non Sequential Conversion
High Flow Intake
Efini Y pipe - No CAT - Blitz Exhaust
ARC Stock mount Intercooler & Piping
High Flow radiator
Apexi AVC-R Boost Control
Alky/Water Injection
Upgraded Fuel Pump
I expect 330RWHP under these specs...
What can I do about fuel tuning ?? Does any of you have specs like these under PFC ??
Am sorry for so many questions, but in this part of the world rotaries are not very popular...
Thanks..!!!!!!!!!!!

you would be best to try to find someone who can tune it or learn on your own slowly and carefully. a good timing map is all you need and time to learn how to tune the fuel curves on your own. the stock PFC maps are ok for the twins for moderate power levels, once you start pushing over 300whp the timing should be pulled a few degrees in the 5500RPM(peak torque) range.
any issues with the fuel system will result in a blown motor if you try to use a premapped ECU or someone else's maps.
you also mentioned SAFC first so some confusion is probably evident. an SAFC is a piggyback and only works on air flow meter/mass air flow meter equipped cars, the FD has a MAP(manifold absolute pressure sensor) so an SAFC won't work. i assume you did mean Apexi power FC which you mentioned later which is a standalone ECU and not a piggyback.

So you think there´s no way I can get a Pre Tuned Power FC ??
I probably won´t be 100% fine tuned, but it would do the job if I provide my specs ??
Or is it better to get a Chipped ECU ??

just keep your stock ecu and limit your boost to 7 psi. this will allow for spiking since you are not running a cat. or get a pettit ecu and limit your boost to 10 psi. the problem you are going to have is fuel since you are running a straight exhaust you are going to spike on boost. the stock injectors are going to max out so keep your boost in check.

I can set boost with the ACV-R... But with 10PSI I´ll need extra fuel ??

Yes, you can get/find a PFC map which is "similar" to your setup. However, just because it's similar doesn't mean it's "safe". If you want to invest into a PFC, you need to also invest into a datalogic and Chuck's Tuning Notes for the PFC. That way you can start with a similar PFC map and understand how to fine tune it for your car.
You mentioned you do have some rotary experts in your area but they don't have PFC knowledge. What programmable ECU's do they have rotary experience with? If you go with what they know, then you can get local help rather than relying on internet help with the PFC.

Well not a big eperience on ECU´s really. But from what I heard, rotary tuner would feel comfortable with MOTEC ecu.
But I don´t really think want to go that way...
Regarding reflashing ECU´s, do you know if they have to be specifically tuned for Non Sequential twins ?? or that´s something won´t affect the performance of the ECU ??

Do you have the specs for the MAP you have ??
So, my understanding is by getting the PFC and Datalogit I can load & modify the maps... So the Palm would work as a "Gauge" ??
I like the idea..!!!!!!!!!!!
