What wave forms should I see, for these triggers? TDC, (I would think 1 ref per tdc event) CKP (24 evemts per 720 degrees), CYP (1 event just before #1 TDC) Is this correct?

98 Prelude H22 supercharged, Hondata OBDII computer with internal OBD I to II plug, S300, socketed by Hondata. DTC error #9. I've checked triggers and wiring at ECU connecter with osciliscope and have a good wave forum. Any ideas why I still have CEL and error code?

I guess if I read the manual and could remember all of it, I could have solved it myself. Anyway, thanks for the help. Removed RP17 and RP18 and installed a jumper in RP18. That fixed DTC 19... But I still have a DTC41 with the O2 disablied in the closed loop tab. Am I still missing something? Also ...

Do you know what jumper I nedd to remove or add to make it a stick ECU? I disabled O2 in closed loop tab, but DTC 41 still comes up, any idea?

How can I have a DTC code 19 with a stick shift? Can I run open loop and bypass DTC 41?

Will the K-series work on a 2004 Element? Or should I swap out the ECU to an OBDI?

Well, I have my customer's vtec at 4,400. I first shut it off (8000) and tuned the non vtec map, then turned it back on (4,400) and tuned the vtec or high fuel map, he says the car pulls harder than ever, and he has had every chip and computer in the world on it before... Other tunes did some of the ...

If you check on the main web site, it has applications by engine and/or by vehicle. You also can check by looking on the part number of the ECU to see which one you have....

The engine is a B18C1 with skunk2 cams. The driver wants the v-tec lower so that he can make more power lower, for drifting... The intake butterflys are out also...

What is the lowest RPM you can get the v-tec to work good on a B18C1 N/A engine. I've tuned mine for 4500 rpms but I get a drop in the power graph on the dyno. You don't really feel it, but it looses about 30HP right after v-tec comes on. Any ideas?

Is there any newer instruction manuals than whats on the web site. It's for the 2.5 version, and I have the 3.5 version. The resond I'm asking, is that I can't get the datalogger to connect. I;m using Keyspan adapters, comm1 for the romulater and comm4 for datalogger. Just doesn't seem to want to ...

Your problem is probably the belkin adapter. I had one on my laptop (no serial ports on computer) and I had alot of the same problems tuning Accel DFI's. Switched to Keyspan (Comp US) and no more problems (also the recommended brand by Hondata).... hope this helps!

You can use any male 3 post weatherpack connector, just have to cut slots in the poles to fit your MAP. GM used them on 1985-1996 TPS sensors, 1,2,&3 bar Maps, and misc. accesaries. Black for TPS and misc. and green for 1 bar, red for 2 bar, and orange for 3 bar. If you look at the terminal side of ...

Thanks to Matt and Doug, I'm up and running! Used the wrong version on the ROMulator software, and had a bad solder joint on my ECU... I guess I'll learn to do that better! Anyway, car is tuned and gone!
