First of all, here's my setup: Toda Spec A camshafts, ITR springs/retainers, Skunk2 Cam Gears, PYR Racing p72, AEM CAI (now stock because I ripped my fender lining out somehow), Tanabe Racing Medallion.

Last week, I got a reprogrammed p72 from a guy on H-T which shifted VTEC, changed my fuel map, and raised my rev limiter. I've been told by numerous people (on HT) that my valvetrain can handle RPMs of up to 9k. I've only brought it up to 8900 once, and I don't think I'll do that again (no reason to). Anyway, I did a few runs through the gears to see what the ECU did for my setup, and I shifted on average around 84-8500. Afterwards, my car started to idle kinda funny. The note my exhaust makes is kinda lumpy, but my RPMs aren't fluctuating. Because I already bent my valves once, I'm kinda freaked and I'm not sure if I'm tricked into hearing things or not, but it seems like I hear really soft ticking. It's nothing like when I bent them on a 3rd to 2nd misshift though. Even with all this, my car pulls really hard, so I don't know what the problem is.

I've since then swapped the ECU out for my stock one because I've had to drive long distances, and my gas mileage was getting owned. This seemed to help quite a bit. The exhaust still makes the lumpy sound though. I don't hear any misfiring luckily, like when I had bent valves. I also did a check that my friend did when I bent my valves where the spark plug wires are pulled while the car idles. If the cylinder is operating correctly, the car should struggle when a wire is pulled, and it did, for all four of mine. I also did that "screwdriver test" that people on HT have talked about, and I'm not sure what I'm supposed to listen for, but everything sounded pretty normal when I did it. All this leads me to believe it's not my valves, but then what could it be? I'm thinking, it might not be bent valves, but the 8900 RPMs thing might have thrown them out of spec. I've also heard that it could be a timing issue, and also that injectors tick pretty loudly. Could the ECU have done something to them permanently? I don't have any tools to fix the problem, or any money right now, so I hope it's nothing major because I need my car to get around. I also don't have the know-how to do the work myself. Anyone had any symptoms like this on their car?

PS... I'm trying to get some things together so I can give you all a timeline of what happened since I bent my valves last January, just in case anyone is in the same boat. Overall, I'm very happy with the result of things (even the gas killing ECU), and can't wait for the track season.

 

any opinions on this?

 

Sounds like you have a problem worth asking about. BUMP for you buddy. Good luck

Thanks homie... here's another bump. Sorry about my wordiness, but if anyone has the patience to read through it all, I would like some advice or input if possible.

 

I can't hear your engine for obvious reasons. But if it isn't to bad it might be a timing thing since you have bigger cams than factory. (If you have a gsr or ls w/type r cams.) I know when i got my cam gears my idleing was different than when they a set at o degrees. that is my opinion and somebody might have a better one so still keep an open mind.

 

damn, no love from the Integra forum this time?

 

One last bump.
