I just did a swap with a friend. He has a 94 civic coupe ex, he blew his motor up last month and just rebuilt it. So we swaped it back in on sunday, it has a new comp cam, arp head studs and arp rod bolts. It's also boosted with a budget dsm setup, so he has dsm injectors with resistors. Now my question is, we're having a problem with going over 2000 rpms, as soon as it reaches that it starts oscilliating from idle all the way back up to 2000rpms. but anything under 2000 rpms it runs just fine, well kinda rough but understandable.

sorry if this isnt very clear, im in a huge hurry and will fix it later.

 

what was done for tuning?

we unhooked his turbo so he wouldnt run any boost. so basicly a stock p28, we put in his uberdata chipped ecu with a basemap and it ran even worse and did the same weird thing at 2k rpms.

 

id have someone move this to the fi section, your going to get a lotter better results, specially with this technical of a question

good luck and happy motoring

 

its not even remotely related to his boost, considering the turbo inlet isnt even hooked up and its useing the STOCK ecu. Anyway, we figured out the problem, turned out his old and gay pos apexi vafc that he is removing was ******* it up, so we unwired that, and it worked fine.

 

my buddy had the same problem. it was his ecu. change ecu to see if that will change anything. that solved his problem
