Hondata

I'm curious to know if there is another way of controlling the IAC without using the Hondata System. Is there a way of connecting some kind of resistor or something to increase it's duty cycle?

Thanks

I'm using the P28 ECU on my 1993 Honda Prelude H22A1 and I would like to know if I could burn a US GSR Rom into my P28 ECU? Thanks.

we have recently started using hondata and are running into a pretty big problem. here it is.
95 H22 stock bottom end
obd1 P72 started with base boosted GSR map
830cc injectors
intake and inline pump

fjo lambda meter

we tuned the low cam without a problem. car ran in the high 11- low 12:1 a/f ...

Where can I find the H22A 720CC Base map? Could you e-mail it to me? lovehonda7407@msn.com

I need it! I'm using the P28 ECU, Stage 4

Does anyone have a Rom for a stock JDM H22A engine and a USDM stock H22A engine?

The sensor itself is 5 wires with a 7 pin connector (the extra two are for a calibration resistor). But the sensor plugs into the DIY-WB box which has 2 wires as an output (ground and signal).
I don't remember what value resistor I used for the connector. It says what to use in the Hondata manual ...

Yes, it is the factory O2 sensor plug. I got it off of an old sensor from my car. I just replaced the sensor and cut the connector off of the old one. I put a resistor on the heater wires to convice the ECU that the heater was still there and connected the other two wires to my WB.

The DIY WB will work on any car. You will probably just need a different connector to plug it into the factory harness. You could probably find one at a junkyard.

When I want to tune my car I remove the front sensor (the one before the Cat) and replace it with the wideband sensor. I connect the ...

I have the techedge kit. I love it. You can even get it assembled now with a case and everything. You can't beat the price and it seems to work great. It agrees with the dyno dynamics wb on the dyno that I go to.
It was easy to interface, I just took the connector off of an old O2 sensor for my car ...
