I juts had a street port and power fc added to my 94. I have been breaking in the new core but I have a question. The injectors were upgraded to 1300cc and I had a Nipo fuel pump added with BNR stage II turbos . The car is running on the base map and it seems to be flooding on cold starts? The other problem is on warm starts, the motor revs to 4k then drops to 2.5k back up to 3k then drops to regular idel . I think its just set to rich , but I thought that was the safe way to go until I have it tuned at KDR . I should have 1500 miles on the new core bye then . Any thoughts ?

mine does the same, but i blame it on the gas pedal being stuck, not the p-fc itself. my mods are almost the same as yours and it does almost the same thing.

humm, Jason aka rx7 store suggest I rev it into the 6k range.He thinks it part of the PFC softwear setting up since I have been running under 4k for my first 600 miles on this new core .I deffinatly know this is not a throttle sticking like papasmurf mentioned.If you tap the gas when its going threw this cycle it doesnt effect the fuel flow ,it just starts a second rev cycle like the first one .If your throttle is sticking papasmurf you need to get that fixed.It could bit you back hard some day . I just changed my oil so I guess I have a excuse to rev it a bit higher , but I have kept my boost down to 5-7lbs .Just a little suprised othe PFC useres havent seen this happen

bump....help https://www.nopistons.com/forums/pub...1047683473.gif I want to drive https://www.nopistons.com/forums/pub...1047683358.gif

my pfc has now learned the car and im about to do the second oil change on it (now close to 500 miles on the new engine, about 130miles a day to get it done quicker), the throttle actually fixed itself somehow and doesn't stick and the pfc has no problems i can find now.. i surely hope you get yours fixed, sorry i am no help with this.

when i had the PFC it never did that.... i'd say drive around and give it some gas see if it clears up
