Obd1 tuning (after cams)


Recommended Posts

Hi guys. I know this has probably been covered 1000's of times, but after searching I can't find much info, or the info I need.

My cars a 1992 Obd1 vr6. I plan on doing some pretty basic n/a mods. Cams, manifold, exhaust etc. But how do I go about sorting the software afterwards? Pretty sure these can't be mapped through the old port. So am I best to chip it or?

Info appreciated from people that's went down the same route.

Cheers

There's a link to pretty much the full ecu in the remapping thread, also on clubgti in vr6 area seeing as you have posted this there. Think it's in English too so you either go about tweaking it by creating your own def file from it and your own flash or someone chip it being older m2/3 or some go the megasquirt route as there is less to tune on aftermarket systems to get a decent tune.

 

The older motronic stuff is very similar and this is a good thread where I got my info from;
