what is the differance between the obd1 ls and gsr ecu. I work at a parts
store and we dont have them on hand so I cant physically look at it, but
I had noticed that the part numbers were different?

So could somebody point me in the right direction

 

the ignitor part numbers aare different. i think that is the only difference.

 

the ignitor? as in the coil, right?

oh whats the differnence between the two? does the p72 have a stronger spark or something?

 

The p72 is a GSR ecu with v-tec and reads knock sensor.
The p75 is a LS ecu and does not have v-tec and does not read knock sensor.
If you are doing a LS/CRV V-tec conversion p28 is the way to go, the obd-1 p28 has less sensors to worry about and does not read knock sensor. If you happen to do a frankenstein swap make sure you program the p28 to add the more air/fuel curve.

 

ok well i wasnt exactly asking about the ecu's

just whats the differnece in the distributors.

but what do you mean by programming my ecu for more air/fuel

are you talking about tuning the car with like hondada or chrome?

which im not exactly at that step yet. Im going to be buying the s300.
(as so as I get the money)
