so my homie and I are having a debate on an ECU. you see I need an OBD1 LS ECU. at first the P72 was brought but that is no dice (VTEC ECU). then he said P75. I say P74. my debate is the P75 is the OBD2 version. he says it isn't. any help?

not to be a dick but you could have answered your question by typing obd1 p75 into google...

so yes a p75 is obd1, i have a obd1 ls and have a chipped p75

 

i did google it. but all the comments out there are so stupid. you got some people saying yes, some no. i went to a better source.

 

ok well im telling you i have an obd1 ls engine and engine harness running a p75

 

Here is a good ECU info source; PGM-FI.org

You will see that there are both OBDI and OBDII P75 ECUs. So you could pick up ether an OBD1 P74 or P75 and you'll be good to go.

 

see this is more like it. i was beginning to wonder if the P75 had both OBD1 and OBD2 versions.
