Need a temporary map.
I hate having to ask for a map specially since I dont have a datalogit, but heres the thing. My FD caught on fire a few weeks ago and it seems that my Apexi PFC has reset itself? Or possibly the shop reset it idk. I'm running 850cc pr and 1600cc sec injectors but the pfc has went back to saying im running 550 and 850. Also my idle is at like 1700 and i've tried doing the idle relearn. I dont wanna run it much like this but it is my only way back and forth to work. Luckily i live on base and only have to drive about 5 miles. I need a tune ASAP lol. My mods are PFC, stock seq. turbos, greddy front mount, K&N open filters on the stock accordian tubes, 850/1600, unknown downpipe, racing beat exhaust, no cats and still running a smog pump. Julio was telling me about you tuning his car through the computer, is that possible for mine until your able to get out here? LMK asap. Please email me. mckinley.barker@gmail.com. Thanks.

In your commander for the injector settings at the bottom enter in 797 for the primaries and 1500 for the secondarys, and change the pr percentage to 64.7% and next to that make it +.04. Then when you can get a commander on it you can change those to 850 and 1600.
Did the engine bay catch fire?

Yes all vacuum lines are now silicone and zip tied. One thing I noticed though is the line from the pressure tank says its suppose to have a check valve but my car never did. Is that an issue? I was about to ask about the idle. Its up to 2k

Lol im not sure about that. I know the hose running through the throttle body is disconnected. And it didn't do it before with the pfc. And it don't do it with a stock ecu. Its gotta be something in the tune itself. Any help with doing the idle relearn process? I tried the disconnect the battery, hold brakes, reconnect, let idle, turn on defroster and idle and turn on ac and idle, but it might not have worked

There is another screw hidden where the elbow bolts on. But that shouldn't need adjusted. What did the shop do? Are you sure the injectors were not changed, those settings do work for those injectors, I've used them before with that injector combo.

64.5% works because it tells the computer to inject 64.5% of the fuel, because you have injectors that are 850s instead of 550s, 550/850=64.7. so that's strange.. If you had 850s in there with 100% as the setting then it would be dumping in way too much fuel and wouldn't work.

well it works with 100% and 797 and 100% / 1500 but not the same injector size with the 64.5% 64.7% isnt an option on the commander. literally with 64.5% and the same injector size i hit the throttle and the car just drops rpms.

What are the chances the shop stole your injectors/fuel system and switched out your pfc and gave you a bad one? lol. But seriously that is suspicious, maybe your power fc is bad if it worked good before and the car works good with your stock ecu now.

i doubt all that. theyre a good shop and hes known around here for his work on rotarys and his honesty. dont think he would screw me like that. if its a bad ecu it would have been from the fire grounding out some wires. but i honestly dont think it is.i think i just need a map. im going to take the top of the engine off tomorrow and see what i can find. maybe a hose has come loose but i doubt it.

Ya. But the shop switched up your whole fuel system, injectors and rails, and didn't tell you, and where are those parts now? But if the car runs good and idles good now with the stock ecu, it should run good and idle normal with the power fc too, unless there is something wrong with it. No wiring was damaged? The power fc has a fuel map and 2 timing maps, all of which are not going to make your car idle really high, you don't need a "map". it is all the other settings that could possibly change the idle, but if you reset the power fc all data init then those settings should work fine.

lol the old injectors are a melted mess. yes i have a brand new wiring harness on my engine because my other was toast as well. there really isnt anything that he would wanna keep for himself after the fire. I was there for the disassembly lol. If it cant be in the ECU, then its gotta be somethings loose. I'll dig through and find it tomorrow.
