Re: Hondata s300 on P28 working for years then died during t

So, just as an update: the s300 w/ the serial number listed in the first post is definitely bad. Can I get an RMA#?

Re: Hondata s300 on P28 working for years then died during t

OK... so we can't really explain it, but we tried several combinations of clicking update USB driver, uploading calibrations, and s300/ECU combos and what we think did the trick was that the s300 *EDIT* spare */EDIT* needed to be "reset" by plugging it into a different car. As soon as we d...

Re: Hondata s300 on P28 working for years then died during t

So i guess i do have a follow up question: assuming it is the vehicle's wiring, what, aside from the Helms chapter 11 circuit checking, would you recommend looking at to debug this issue?

We should know more by COB today. Thanks for the confirmation on whether or not the s300 will screw up the harness.

Hondata s300 on P28 working for years then died during tune.

ECU: P28 Hondata s300 serial number: S300-0516 Vehicle: 1994 Acura Integra LS 4-DR B18B1 Non-VTEC History: This ECU/s300 combo was tuned and powered my car for a few years without any issues. After installing a new turbo and some sensors, we were pulling the car onto the dyno when what felt like a p...

Dude... I'll mail you a spark plug socket heh

The right tool should not be the impediment to you solving your issues. I have spares, just PM me your address on TI.

OK, so I think I have determined the sources of the problems. One of them is definitely the IACV and there is also definitely something going on between the wideband controller and Hondata. I hooked up my OEM narrowband O2 and used that as the narrowband input to Hondata while I still had the wideba...

Are you getting any check engine lights>? You need 5 things for VTEC to engage properly... VSS input (i.e. the car is moving forward), MAP pressure (WOT only), oil pressure (VTEC solenoid), and there are two others which escape me now. also, do you have a wideband O2 hooked up to the car? what are y...

yes, i agree. however, i have been able to notice the problem at low throttle in open loop since that first post. compression and leak down is on my list of things to do and i also highly doubt the injectors are at fault since i just put in the sonic cleaned ones from RC and experienced the same pro...

perhaps i'm not being clear. open loop means that the O2 sensor is ignored (thus long term and short term fuel trims ignored) and the AFR is purely dictated by the fuel vs. pressure map and various correction factors, right?? So, my question is this: is a dying O2 going to actually make my car run l...

granted, however, would that explain running lean in open loop?? could there be some screwed up wiring that somehow affects say the 12V switched supply to the fuel pump or something?? I have received a replacement wideband O2 and will be re-installing my OEM narrowband as well to try to determine if...

However, the fact remains that I am still having issues at low throttle. I am having a second O2 bung welded onto my exhaust so I can run the OEM narrowband and still watch the AFR on the wideband. This way, I'll be able to see if the wideband controller is bad. I also noticed a slight leak in the f...

You cannot use vtec pressure as an input for the wideband signal. You must use one of the ones listed in the software. Vtec pressure is not an analog input, it detects an on or off signal. I lied and spaced out. I use D6 for full throttle shift. I use ELD for wideband in. Sorry for the confusion.

I am using a PLX M300 wideband, currently using the narrowband output (gray wire) as the closed loop input for the ECU. The wideband output (white wire) is running to the D6 (VTEC pressure) on my LS. The calibration will be up shortly. Thanks.
