Hondata

nothing from the far reaches of tuner land? Any help would be appreciated!

Car specs:

B16 w/ built bottom end (rods and pistons)
Vortech @ 13-14 psi
RC 550's with Walbro 255
S300 obviously
hacked up calibration by me that I downloaded from here and got car running
Self socketed P28

Background:

Been running this "tune" for a while but have had problems with it for a ...

You'll have to make adjustments to the basemap as not every car/setup is the same. Make sure you have a wideband so you can see how it's running. You can make crude adjustments to get the car running, of course, if it's a long drive and you don't trust your tuning ability then you should trailer it.

I don't have a map for you but once you obtain one, open it in smanager and under "Online" select "upload" or simply ctrl+u. This will load the calibration into the ECM. This is also how you upload any changes to parameters,settings, etc.

Now that wideband input is working, can someone clue me on how to get some fuel in this beater, it's running full lean!

I've tried changing the overall fuel trim, cylinder trim, some water/air temp compensations without much success. I'll run cylinder trim up to 25% positive and the computer will ...

That was it! Damn "minor details"...they'll get ya everytime!!!

Corrected solder joints and test drove-still no voltage input reading from S300 even though back-probing connector to P28 shows voltage. Am I inputing the signal to the correct pin? (see attachment)

Thanks!

Double check your wiring because you are not getting any voltage reading from the ELD input.

After having some running issues I was finally able to check my wiring from gauge to input D10. Checked voltage output from gauge to input of P28 and voltage is corresponding to A/F ratio.

I've traced ...

A short datalog showing no A/F ratio change at all.

You may have it wired to D10, but you have the software set to have the input on D14.

Sorry, reading off an old calibration and changed the input to D10 but didn't save. Below is a calibration with D10 selected and still the same result.

Also, any advice for the previously mentioned lean ...

If your rev limiter is set to fuel and ignition cut then I believe that's your situation. The signal is cut to your rev counter, I can't remember the exact explanation without reading it first hand, correct me if I'm wrong.

are you sure your at d10 on the harness and are you setting the hondata config to read off d10?

Double ck'd the pin for D10 and traced it through the jumper harness (OBD 2 vehicle) to the corresponding pin at the original wiring harness and specified D10 as the WB input. I'll have to get an ...

I hooked my AEM 0-5V output into D10 of the ECU (removing original wiring), cut R136 and R138 (what I understood to be R136/138) and loaded the calibrations of 0.0V=10.0 AFR & 5V=19.98 AFR as per the manual's table (correct?).

My gauge is still reading the same yet in the sensor window of the S300 ...
