Hey guys had a swap from a civic ran great no issues I’ve done tons of engine swaps so I’m not sure what I coulda done wrong but my 91 integra seems like it’s hitting a fuel cut like I’ll floor it and it hesitates bad unless I inch up on the throttle slowly. Also it used to have a crackle tune ( i didn’t do it) and it stopped doing it so is it a fuel issues? Could different type of gas cause it in upper rpms I can blip the throttle and it will do like little back fires but I’m just trying to figure out why it’s not running right? The civic didn’t have a fuel pump or anything like that and it’s turned on a s100 so of course idk crap abt what the tune is I didn’t do it but if anybody has any info lmk thank you

 

i had a similar issue turned out the tps was going bad.
currently running a dorman unit, it's pretty solid.

Alright thanks for the help I’ll give that a try

 

I had a really weird instance where my tuner's laptop crashed on him when he went to make a change on my tune on S300 and it corrupted the file and somehow made my car redline at 6k RPM, we didn't think anything of it after the tune since the file looked right. Luckily it wasn't a hard fix for him.

 

I’m not sure how I could even change it the tunes on a s100 like old f1 80’s stuff I’d have to wait till I can get a hondata or a moates demon

 

use a stock ecu and see if it is still doing it.
