You can buy a p75 ecu. I personally would buy an ecu that can be chipped then chip it and run the p75 basemaps on it. Later down the road you can tune it. Here's a list of ecu that can be chipped
chipable ecu's
USDM, EDM, or JDM
Non-VTEC
P05
P06
P09
P1K
P27
P29
P54
P74
P75
PR4
VTEC ECUs
P08
P28
P30
P61
P70
P72
P91
PR3

This maybe a dumb question but does it matter that my car is not vtec with a vtec ecu ?

also is the one you are reffering to off the last gen integras?

I would run a non vtec ecu. My can ran great with a pr4 ecu. It's from the 90-93 teg

p75 came in the 92-95 integra ls and gs

The way i went about it was i bought p06 ecu off ebay and then i bought this chipping kit
http://www.hamotorsports.com/usdmchipkit.html
And i bought a chip that had the p75 basemaps loaded onto it from here

Then i watched this videos on how to chip an ecu like this one

That's basically what i did.

so basically the chipping kit makes it easier to mount the chip and the chip goes on top of that thanks !


does it matter where on the ecu you mount the chip or is there a specific location that it should be mounted ?

thanks for the info.

if you dont mind me asking what did you pay for the ecu ?

Any 0bd1 ecu will work. Vtec or non vtec. It does not matter unless you plan on a swap later. Vtec can be disabled on any quality management program. The 4th gen accord distributer seems to work best for the swap. If you search this site, i am sure there is a thread that goes over all of this.

[elpuma]

Everything has a specific location where it needs to go to. This is from the HAmotorsports website that tells you step by step how to chip an ecu with their products. It includes close up pictures.

ok thanks guys really appreciate it.

well for non vtec ecus around here they cost 100-150 and Vtec ecus are around 120-180.

I had a virgin pr4 so its from a OBD1 90-91 LS integra and the p75 is from the OBD1 92-93 LS integra. if you have alot of mods you might just want to get a chipped ECU so like that you can tune it.
