Hondata

I was never able to trace the root cause of the problem i was having... but i can tell you that it was solved by switching to a s200 with a new, well tuned map.

AndyE, thanks for the lengthy response. I think that tuning is my problem, but unfortunately I don't think its the same precise problem as what you had. As a matter of fact, I captured some WOT runs yesterday, and just took a look at the LTFT. Its 3.2%.

I have a similar setup to you. 99 Civic Si ...

AndyE: Did you ever track down the problem? I still hear what sounds like a mis-fire at wide open throttle and I'm somewhat at a loss on how to troubleshoot it.

Email me if you have a few spare cycles.

I never found out a sold number either.. however I can tell you its hard to find the right size. Truthfully I dont remember what ended up going on there. I ended up buying a different size belt from every place in town, I think I may have ended up going larger (like 640?!) but I found a trick:

By ...

I am also running a colder plug.. however with a larger gap due to the MSD. As for the fuel question, im running a Bosch monster pump, im sure its up to the task.

My problem began when I solved belt slipping on my ~8.5psi pulley. The belt had been slipping since day one, and unfortunately I tuned ...

Jag,

I live near Hartford, CT and have a 99 Si with a B16, JRSC, and Stage 4 badly in need of tuning. I was wondering if you might have a free afternoon to lend a hand in tuning. Perhaps I can entice you with free lunch or the satisfaction of helping out someone in the scene. I'll probably be ...

I did run into a problem with the tach not working with my J&S Classic and Hondata. The fix is simple. It requires a single resistor used as a jumper across two wires going into the J&S. I don't recall the Ohm rating, but try doing a search with the word resistor on Hostboard, ClubSi or Honda-tech ...

Unfortunately, I have very little time lately to work on the car.. so sorry for the delay, and I dont have much to share.

But here is what I do know. I took a look at the plugs today. They dont look good. They are black, except for a pure white on the center electrode. The top electrode is worn ...

i am using a MSD 6al with blaster coil. Someone at Hostboard mentioned a similar problem when moisture entered the cap through the holes drilled for the wires. I dont think that is my problem though.

Its almost uncanny. I posted a message at Hostboard with the same title even.

I have a 99si, B16. JRSC, stepper pulley, that is experiencing the EXACT same symptoms. However, I know exactly when my problem started. I had the car tuned back in spring by Tom Payn. It turns out, I think the blower ...
