Hi so i have a 1991 honda civic si with original engine and ecu. It is a pm6 ecu and i know you can't chip it cause i took the ecu out and there is no where to put a chip. So how can i tune my ecu. I'm going to put an ebay turbo kit on it for fun and i was going to buy hondata s300. But now that i know my ecu can't be chipped what can i do? Can i buy a obd1 that has a hondata v1 already chipped in it. Or do i need to change the ecu completely? Is there a cheaper way to tune my car? What can i do?

 

You can buy an OBD1 ecu that is already chipped but you would then need to buy the OBD0-OBD1 jumper harness.

 

What obd1 do I need can I use a p28? Or no will that not work? Do I have to use a obd1 p06? Or which one can I switch it too

 

It will depend on the engine you are running. IF you plan to run a vtec engine then a p28 would be the best option. You can chip a pm6 as well, there are a few places you can send it to for this.

Ok so I have a d16 1991 Honda Civic still original engine? I know if this blows I'm willing to put a new motor in it my next engine will be a d16 again but a newer one probably a y8. So can I run a p28 on a 16 valve d16? And so it will work on the next engine or no?

 

you can chip a PM6 and run turboedit. I won’t say it’s “worse” than running OBD1 it all really depends what you can afford and are willing to do.

 

How do you chip a pm6? With turbo edit? Where do I get that and how?

 

turboedit is the software you will use to tune like hondata, neptune, crome etc etc. in a nutshell you will need a way to burn ti a chip. a chip, either a demon or ostrich if your trying to tune "live" per say. check this link and enjoy the reading.

Ok so i am kind of confused? I can chip my pm6 ecu cause its a pm6 obd0. Ill go to obd1 once i put the next engine in. But where and what chip do i buy for my obd0 every chip i see is for obd1? I need a chip for a pm6 obd0 for turbo edit?
