I get the stuff from the track. It says SUNOCO & they told me it was 109 octane. They probably have their info wrong, the guy who pumps the gas isn't the brightest. As for the car, I have now completed 2 whole race days for a total of 143 laps, placing 2nd the one day & 1st the other day & not...

I could be wrong on the whole octane thing. I was just making a guess, It's probably 110. As for the ethanol part, yes it does affect the way ALL my vehicles run & has at one point or another affected every car in my racing class. The cars start running rough, chugging during acceleration &...

There is no lead in the octane booster, it's actually not even "octane booster" that I'm using. I add 1 gallon of 109 race fuel to 4 gallons of 92 pump gas. The race gas burns so much better than just straight up pump gas. I don't know about other states, but around here the pump gas has so damn...

Excellent!! Well I should know for sure if the limp mode problem is solved tomorrow, we have another race & it's going to be a 75 degree day. Thanks for all the help & I'll let you know if the O2 sensor & air temp sensor solved my problems.

Sorry, it was 19inHg at an idle & under a load was 9inHg, holding the throttle about half way, with it in gear & the ebrake on with wheel chalks. The key on, engine off reading was 30inHg.

I would love to get a nice, tunable ecu, but the fact remains that the track rules strictly forbid chipped or programmable ecu's in my class of racing. So basically I need to make this thing run right on a stock ecu or I just have a very expensive pile of crap sitting in my shop. Renting the...

Ok, I built this car from scratch 2 years ago. Motor was completely rebuilt & when I first put it on the track last year it was cold & wet cause it's the Pacific NW & the car did excellent, no problems. Until about May when the temps started increasing & we were racing harder, then this weird...

A few more tidbits.... My idle air control solenoid quit working earlier this year, I have replaced it many times with know working ones & every time the coolant temp reaches about 175 the idle starts going up to 2500rpms, then drops dramatically to 600rpms, then back up to 2500rpms, then back...

No thermostat. We can not have antifreeze in our cooling systems on the track & last year my brand new thermostat rusted up & caused the motor to blow a head gasket, so this year I'm not running one. My crankcase vent doesn't go into the intake tube anymore, instead I run it through an oil...

I have an aftermarket gauge, so the stock sending unit isn't even hooked up. I run about 90psi under load & 50psi at an idle. Not sure of the oil temp. I use Mobile1 5w-30 synthetic & change it every other race.

I don't know much about the Hondata ecu, my buddy came by with his Prelude to help me & we decided to pull his ecu to see what would happen. He told me that his program would run my motor just fine & it did, until my engine hit 5300 rpms at a temp of 185, then the same thing happened - limp...

Let me make this very clear.... Hondata ECU = limp mode Stock OBD1 ECU = limp mode Stock OBD2 ECU = limp mode Every single removed sensor put back = limp mode My modified engine = limp mode My friends 100% stock engine = limp mode Stock ecu or chipped ecu MAKES NO DIFFERENCE. Stock engine or...

Ok, so I changed the plugs to standard NGK's & replaced the coil & the car still does the same thing. It never sets a code. RPM's limit out to 3300. It does it with a stock P14 ecu, both OBD1 & OBD2 & also I borrowed a chipped OBD1 ecu & it does it to. Tried watching the scanner to see what the...

Yes it is very hard to diagnose & there is another Prelude just like mine that races with me & his car does exactly the same thing as mine, almost at the same time on the track even, but his is completely bone stock. I have a new MSD coil, new 10.2mm spark plug wires & 4 new NGK Laser Platinum...

I have a 96 Prelude with the H23A1, OBD1 ECU with conversion harness & I've been battling this strange running issue for quite awhile now & I just can not figure it out!! Please watch this video to hear what it's doing. http://youtu.be/XJse0SPER3k The car starts out fine, then it does it's...
