p75 auto ecu for manual swap???
I've got a line on an obd1 p75 that I need for my LS swap in my 93 hatch.
I'm doing a manual transmission swap but the ecu is an automatic ecu.
will there be any problems with using this ecu?? I would go with a manual ecu but I can get this one for literally half price....so obviously if I can use it I'd like to.
Will I need to change any ecu plugs or anything or will there be any engine codes thrown and any sort of limp mode or what not??

Re: p75 auto ecu for manual swap??? (stackz)
If you run this ecu you will be throwing a code if not a few.
If you didn't buy it yet, save some money and buy the proper PR4 or P75 manual ECU
The plugs will be the same, as long as it's OBD 1
92-93 integras were obd 1 and have a pr4 ecu you can use..just make sure it's 5-spd
94-95 integras were obd 1 and also have the p75 which you know of but would be best and less time/money wasted to buy the proper manual ecu to begin with

Re: (v4lu3s)
so I can run EITHER the PR4 or P75 OBD-1 ecu and have the same results??
If I use the obd1 pr4 will I have to swap injectors or wire in a resistor box like with the obd0 pr4 ecu??
what is the difference between these two?? ignition curve??

The 92-93 integra engines are rated at 130hp. The b18b 94+ are rated at 142.
The only difference between the ECU's is one is from the 2nd generation integra and the other 3rd generation. Both are OBD 1 and as long as you get manual it will run fine.
The difference between the b18a and b18b is the more agressive camshafts and the intake manifold runners are shorter I belive.
The fuel cut-off is on both 6800 or 6900 but just under 7k.
Check out my thread I made with the exact same question when I was putting in my b18b.

Re: (Mr.RHTuner)
or if you know somebody very good at soddering, you can have the p75 ecu turned from automatic to manual
