Hey guys, I have searched around and really can't find the answer I'm looking for anywhere. I have no clue about tuning but have a really simple question. I put together a street car and have been out of the game for a while. I used someones setup and old hondata s2b ecu. The car won't idle and shuts off when letting off gas so I think the ecu just needs an tps calibration. Is there anyway to still tune this old hondata ecu with the bridge and chip setup? I don't have the money to go to s300. Is there an another ecu program such as chrome or uberdata that i can tune with and burn a chip for the ecu just like the old days so I don't have to spend money and get another ecu modified?

 

TPS check/adjustment only needs a volt meter.

 

No with hondata you have to set the throttle percentage at closed and open throttle. The ecu wasn't tuned with my setup therefore if it's off the problems I am having may occur. With a stock ecu yes it can be calibrated with a voltmeter. Not to mention I have no idea what the minimum idle or IACV duty are set too.

 

anyone?

 

With the old romeditor that s2b came with (if I remember correctly). The tps calibration settings were not in the software for the romeditor which was available at the time.

You need to calibrate the tps to .45 volts at 0% throttle and 4.5 volts at 100% throttle on the signal wire (middle wire).

IACV duty was also not a feature back when s2b was out (if I remember correctly).

I believe the problems you are experiencing is that you are using an ecu/engine management that isn't tuned for your specific setup. Furthermore you may have other underlying issues which really may need to be diagnosed in person.

Upgrading to s300 is $395 & worth every penny.
