So i got a 1993 mazda rx7 the other day its running lean and needs tuned, it has a full high flow exhaust, Non-Sequential turbo conversion, and all the emission controls have been removed. It runs okay but idles rough and will slowly die if left at idle, all i need is to have it run a little better so i can drive it to Banzai Racing to get it professionally done, i cant trailer it but i wish i could. so i was wondering what i should tune the power fc to.

 

If your running lean, do NOT drive it. Rotary engines are really sensitive to knock. You typically don't get a second chance. The lean condition could be due to something other than "just needing a tune". Besides, you didn't mention having a wideband and datalogger.
Since you apparently bought the car running like crap and aren't familiar with them, the safe move is to rent a trailer to get it to Banzai, and let him sort it out.

 

I think you would better take to a rotory shop help you tune it.

 

Purchase a wideband and data logger immediately. Buddy of mime had the same problem until he pop his motor thinking it was the ics that was bad.....GL

 

If you do not understand the parameters of your ECU then do not Touch it and leave it to the hands of someone that Does.
Do NOT drive the car if it is untuned as your wallet will not enjoy being emptied due to you popping the engine and having to replace it.
You know what they say: better SAFE then Sorry.
Don't be sorry..rent a trailer and get it to someone who can tune it.

Case and point: I needed a tune.I got the car running "enough" to drive to the tuner..450km away.
I was too Frugal to get a trailer.I wanted to drive it there.
I burnt up my Turbo due to running high egt's.....cost?..a THOUSAND BUCKS..
I got off Easy.

 

agree, don't take the risk it will cost more in the end
