Hi everyone

Anyone out there prepared to share their PFC maps with me if they have similar mods to mine (see sig)

its still on the base map at the moment and waiting for a tune. down here in my land not too many tuners with both rotary and PFC experience, so im in great need of some help.

the car has an AFR guage (LED type)..on the oem equipment it was running in orange and creeping just into green at full boost. with the PFC installed it remains in the orange band, and at full boost gets to the last orange LED before passing into green. any comments as to whether this is safe or not.

Throw that gage in the trash and install a real wideband AFR meter. I would say you are wasting your time asking for a map, with such mild mods all you really need to do is some simple map changes for idle, driveability, fan temps, etc and then AFR tune. The split map could be cleaned up but the base mod map in the PFC is nt that bad to start with on a stock setup, AFR tuning will wake it up a bit and to do that you need it tuned with a datalogit and a wideband by someone that knows what they are doing.

Nice car.

 

thanks for the heads up twokrx7. recommend any specific guage and wide band ??
i have a 3-pod splitgire gauge cluster installed below the radio with fuel pressure, afr and boost..dont fancy the white face & blue light setup..so might replace entire cluster...Defi gauges look great, but a bit on the pricey side...

With the PFC once your car is tuned the O2 sensor (wide band or not) will not be used as your tuner will de-activate it. So I'd save my money here and spend it on a good tuner (see my sig.) I think that with your current mods the base pfc map is safe and that you stand to gain 15-25 hp with a tune. If it were me, I'd first put on an open intake, down-pipe, mid-pipe or high flow cat. then get a tune. Even with that your looking at a 30-50 hp gain. See my sig. I got 280 rwhp after my first tune with stock primary injectors (rest of the setup was the same).

Don't buy stuff you don't need, have your car tuned by an expert, and have fun!

 

IDK, I don't think I would own a rotary Rx7 without an instaled wideband and fuel pressure gage. These cars are unkind like no other if you run them lean, worst scenario is blowing a motor and not having any indication why it blew, you throw in a new motor not knowing if the same issue will blow the next one. I also like to keep the commander on pk hold for things like boost level and knock.

I just reminded myself why I went V8.

 

Had the car checked out today and AFR's are basically in check with the base PFC setup, thanks for the comments ..one seemingly disturbing thing i noticed was the water temperature on the PFC (now that i have digital readout)..its reading on avergage 100 degrees C at cruising speed and at zero boost, when pushing the car into boost it went up to 112 degreees C..my intuition tells me this is too high..the car still has standard radiator (which i plan to change soon with a bigger core option) and with FMIC and air con in place , is this the main reason for high temps because of airflow restriction or is there something else to take note of.

is it possible to change the fan operating temps with the commander..ive read the instructions and done some research on this site, but im still unsure if you actually need the dataloggit to do this or not. the first reply to this thread by twokrx7 refers to some changes to maps for fan temps...my fan comes on at 99 degrees C and goes off at 91..seems high..whats the recommended settings??

you need the datalogit to set the fans.............i set mine 2 come on @ 90c
