so who has done the obd2(b)-obd1 ecu change? Im wondering because I don't know whats all involved like which ecu to buy or what 'chip' part do I change out?

First of all, what are you doing to the motor requires chipping? What motor is it?

You will need a wiring harness from obdII--->obdI
There's a website called http://www.homemadeturbo.com/forum/i...?topic=31055.0
Go to his website and there are all sorts of goodies for tunning and chipping.

Why do you want to convert?

I'm running Crome on a socketed p28 with the obd2b->obd1 conversion harness.

mainly because I want the ability to tune the motor down the road. Its a B18C1 and bolt-ons are almost done. I eventually want to upgrade the topend (no pun intended) with pretty much skunk2 stage one stuff and for the bottom rods and like 11.1 compression pistons at the most. I only have access to 91 octane and thats the compression type-s' run so i figure it would be safe in the mile high zone. So wouldn't i have to have a tune program to get it running right and making the most power? They say you can't tune obd-2 ecu's really well so thats why. What do you think?

you should already be runing premium. what year is your car?

Topend

Premium is all i use. I can only buy 91 octane here in CO. Its a 00 gsr. Mabye Ill need to do what tweekerz did with the p28 on crome. problem is, i don't know what crome is or the difference between that and hondata
