Ok, I've posted this problem twice before but I still havn't got a solution. The Issue: With the TPS adjusted to .5v the car will not maintain a constant speed. I have a "rev point" at 1500rpm. If I press the throttle enough I can pass by this point without hessitation. This makes it very hard to go slow. Note, I can go to WOT. TPS reads 4.65v approx. With the TPS adjusted to .8v or higher, I can maintain a constant speed. No 1500rpm "rev point". I just can't go WOT. TPS reads 4.98v at WOT, but I know it's going over 5v, causing the engine to just, not do anything. I suppose it just cuts off fuel. *When you turn on the AC your RPMs are supposed to increase, mine does not. Attempted Solutions: Replaced IACV, checked, and tested. Deffinatly works. New TPS sensor. New MAP sensor. Hondata S200 is on the way. Main reason I bought it is to fix these problems. Tuning is a nice bonus. I've set the idle according to the procedure. Modifications That Pertain To This: I've got a 70mm throttle body from a company called Power. I've never heard of them, but it looks well made. Cast, not bored. I had to take the peice that connects to the throttle cable off my old throttle body and put it on the new one because the new one accepted the cable from the opposite direction. Misc Other Info: I've had the 1500rpm problem even with the old TB. I never adjusted the TPS on that one so I don't know of the other problems existed, or what voltage that was set at. Also with the old TB, I couldn't go slower than certian speeds depending on the gear I was in. Example: 4th gear couldn't go slower than 40mph or the car would make you go 40mph. 1st gear went a minimum of 20mph. With the TPS voltage adjusted to .82v like I have now on my new TB, I can go 20 in 5th if I want, it won't make me speed up. So I'm setting a few goals: 1. I want the 1500rpm issue resolved. 2. I want the ability to floor it. 3. Fix the AC issue. The Deal: Here's what I'm going to do, to encourage and repay you knowledgable tuners out there taking the time to read all this. 25 dollars to the person with the solution to goals 1 and 2 before I get my Hondata system hooked up. 50 dollars to the person with the solution to goals 1 and 2 after I get my Hondata hooked up if I can't spot the problem myself. A large thanks to the person with the solution to the AC. After I get the Hondata installed, I'll be more than willing to give out datalogs I will have recorded if necessary. I only posted in this section because my car is a 2000 Honda Civic EX w/ a JDM '95 Del Sol SiR II running on a P30 ECU swapped into it. These issues have been with me since the swap. OBD1 conversion harness. Hondata was ordered 6 days ago from this time of posting. So it should be here soon... So c'mon people!!! PLEASE help me get rid of this!
