i dont really konw anything about chipped ecu's but my question is
i just finished dropping my gsr in my 90's si and i cant find an obd1 p72 around here for sale , except for one tuned with crome... would that in any way hurt my stock engine?
- all stock internals, I/H/E, n1 ctr crank pully. that's about it so far

he said it's already tuned for a turbo charged gsr.

 

depends how it was tuned

 

Try to find someone to put a stock basemap on, otherwise that thing will be running mega rich.

 

You could order a new chip with the GSR base map from many of the guys here. Just swap the chip and you're golden!!

 

you can always cut the jumper and it will return the ECU back to stock.

 

i like the last one....go with it

 

thanks for all the info that's what i figured and i finally found a stock one in state.. thanks guys
