ok guys i have searched and really couldnt find anything with the similar problem. my car seems to start up and when i seem to get near 10 vacumm or 3 quarters throttle it will cut back and not gain any speed. i know it is in limp mode i have been through 3 ecus trying to fix the problem but it doesnt seem to work i know hvae a remapped ecu. what else could cause the problem? could it be my wiring harness or could be something else? thanks in advance!

 

Check the Codes on the ecu.

 

The day after I baought my fd, I crept up on soem boost(11.5lbs), in which I got out of it do to fuel cut at 10lbs. THen I noticed my chekc engine light was on, I couldn't boost more than 7 lbs and it retarded my igniion. I looked at it several times, pulling out the code, i think it was code 5, which is knock sensor. I then took it to the rx-7 store, they got the same code. They attempted to fix the issue, it would work, then moments latter, back in limp mode. Adventually, Jason from the 7store, opened a new pfc put it in my car and he said drive around, see if it fixes it. It sure did, i then purchased a pfc and have has 0 issues since then. My car was saying weak signal from knock. They replaced the knock, and jumped the hanes with a jumper wirre from the know straight to the pin on the ecu. ONce, installed pfc, knock is fine, it counts it.

the only real code it pulled besides the selinoid valves casue my car is non-seq. is 17 which is feedback system for the o2 sensor. but would that make my car go limp.

 

"besides the solenoid valves"....

Didn't you install resistors in place of the solenoids? Doesn't sound like it. List ALL of the codes you are getting -- what you are so casually dismissing is the cause of your problem!

 

17 30 33 38 39 42 43 and i was told that there was resistors when i purchased the car is there a way i can check

 

43 = wastegate control solenoid -- that is probably why you are getting the limp home mode.

If there were resistors in place, you wouldn't be getting codes.

EDIT: Actually, clear the codes by resetting the ecu, start it back up and see what codes are current.

 

that was the codes after i reset it cause i did it when i put back in my remapped but the wiered thing is that it will go a couple of days with out limp and then it will go back in it

 

Time to make a trip to Radio Shack for some resistors and start making sure you have everything plugged up. You should be able to just plug in either the wastegate or the precontrol into the wastegate solenoid connector and take care of that code.

Out of the bunch, that's probably the only one which would throw the car into limp mode.

Are you running a boost controller?

 

Actually, even with resistors in, you will pull the codes...

 

False. That means you either used the wrong resistance or didn't have a proper connection. I have my emissions removed with no codes.

 

yeah i have a home depot special one

 

will my home depot mees it up or something

 

I have 330ohm resistors in place, and I still get 30,33,38,39
