Re: Need Help Civic Si
Why are you running Uberdata and now e-manage? Crome is the way to go...
Get rid of the e-manage piggyback bullshit, aside from AEM... Crome is the only other management I would rec. for a honda.
Who did the tune on your car? Was it a street tune or a dyno tune, or both?
Sputtering is generally an indication of a fuel system problem, bogging is a symptom of either too much timing, or way too little.
It could be your TPS. However, if your TPS is out of range it will throw a CEL, even with a chipped OBD1 ecu... It is doubtful that your TPS would be causing the problem if there is no CEL.
