Obd2 to obd1 conversion

[Hunter1208]

I've been researching alot into ob2 to ob1 conversion.

The car I'm doing this to is a 99 gsr

I've heard that is alot easier to tune plus u can also run hondata which is something I want to do I've heard alot of great things.

so being the over thinker I am I thought I would ask of everyones opinion on here

from what I've read I can just buy a ob1 conversion harness and plug a ob1 ecu into it
also I'm unsure I've I'd have to change the dizzy to and ob1 or not
and I'm wondering what ecu I should use

if I would need to change anything else please let me know thanks

If you have the stock B18C1 intake manifold on it you'll need an obd1 P72 ECU so the secondary butterflies will still operate.

It won't be stock it'll be a skunk2 pro series

do I have to use the p72 with that?
