im trying to convert my obd2 to obd1 and i currently have a p72 ecu and was wondering if it's the same if i chipped it compared to getting a chipped p28? would there be any difference in performance ????

thanks

 

P72 has knock sensor and IAB output. If you're not going to use either of those it will run exactly the same with either ECU once chipped.

 

wat's the IAB sensor and do you know a place that i can send out my ecu to get chipped or is it cheaper to get a p28 chipped for 100$
thanks

 

It's an output, not a sensor, for the intake manifold butterflies. There's plenty of places that offer a chipping service. Do a search.

j-k-tuning.com is one place I recommend.

 

What is your make/model engine ecu setup? is your P72 an OBD2 or OBD1 ecu? I can chip it for if its and OBD1 ecu.

 

I ran a P72 in my civic ek 2000 and was very slow and slugish

you need a chipped OBD1 civic or integra ecu. P06 P05 P28 P30 PR3 P72 etc. the P28, P30 and P72 will all have the vtec components built in. P05 and P06 and many others will have to have the vtec components added to the ecu. The OBD2 P72 ecu that you have will be very difficult to tune and not worth the effort.

thanks for your help and reply but im not to sure waht the base map is i've heard the term on boost with hondata and ect. but off the regular ecu im not 2 sure. and would i still need to get the ecu chipped if i plan to use the hondata s100 or s200 with boost option?

 

Basemap= Ecu calibration that is very close to perfect for your engine setup.

In order to run S100 or S200 or anything else you will need to have someone socket your ecu. I DO NOT SELL HONDATA products and cannot help you if you are strictly interested in using something produced by hondata.
