Default Hondata Map + A/F Ratio - It's running again

Had a local guy come out and help me figure out why the car would not start again. It ended up being as simple as removing the injector clips..turning it over with it floored...then putting them back on.

The car runs, and my FJO WB is reading at about 10.5 A/F ratio. I know this should be upwards of 14.7~ for optimal.

I however do not know how to adjust hondata maps, but I do have the software and a burner.

The rom as it is: http://www.theinvalid.net/basic.bin

Thanks in advance, if you get something you can just email it to me:

Upwards of 14.7?? Noooo WAy! That's wayyyy too lean, you want a solid 12 to 1 air to fuel ratio to be safe when boosting.

14.7 for cruising not boosting

Shouldn't it be around that for idle @ 2k rpm?

I could be way off...**** you guys let me know.

All I know is it's at 10.3~6 @ 2k rpm.

And it burned the plastic off my bumper!..hah...oh well, it's a sign from god to get rid of the kaminari rear bumper and go oem all the way around like i was planning.

yup i know, that's why i would like it if someone could take a look at my basemap and adjust it.

this was the first chip that was burned, so it needs a lot of tuning before i can get it driveable w/out boost and get it to a dyno.

I just looked at your BIN. I changed a lot of things on it but did NOT touch the tables. That is up to you to keep an eye and the AF and make your own changes.

A few things wrong included just some options that I feel should be check. In particular, you were running closed loop so I changed it to open loop. My guess is it was soo rich, the ECU couldn't even compensate for it.

If the engine is cold, it should run between 12.5-13. Once warmed up it should be 14.7 on your wideband.

I sent you the bin back with my changes. Let me know if this helps (it should).

Be careful boosting on a basemap!!!!
