anyone know if there are any differences between an 88 SI ECU and a 91 SI ECU?

and please dont respond unless you know for sure, im sick of bullshit responses like "i think so" or "i dont see why not"

 

88-89 Si ECU's had a slightly different chip pattern, 90-91 are more supported by the aftermarket. Other than that I believe they are all the same.

 

he's right. if you get to choose between the two get a 90-91. Or get a 89 teg ecu....

 

i have an 88 si ecu on my z6...im lookin for a new ecu, or to chip this one with a cheap ebay chip.

do the newer ecu's have a higher rev limit? mine limits right at 6500, whereas i've seen my friends bone stock 91 si go to 7200. also, is the 89 teg ecu plug and play? better fuel maps? and also, whats the rev limit on an 89 teg?

 

A skud im looking around for those cars you have in you sig too.....

The ae86 is sweet but a datsun 510 with a sr20det swap would really haul some a$$....

 

i think the only difference is that the 88 has a dashpod sensor, and the 90-91 doesn't...i think

 

im not lookin right now...im content with my 240...

but, if i got a 510, i'd much rather do the 13bt swap (rx7 single turbo 1.3 rotary)
they are quite fast little buggas
