i've said it before and i'll say it again (maybe on this forum, maybe not).... if you're going to use an ECU with t-vis (like ALL 86 ecu's) then DON'T REMOVE THE T-VIS...... it'll freak the ecu out when you get to those rpm's and it isn't there..... from all stories of those removing the t-vis and not doing anything with the ecu, when it gets to the (~3800?) right rpm's, the engine actually hesitates & slows down.... then it jumps back up accelerating.....

but yeah, it won't be happy that it's not there.... if possible, use a 90-91 ecu..

btw, you shouldn't need a custom harness...... find an ae92 (redtop bigport with t-vis)... the harnesses should plug into the ae86 ecu (same bluetop ecu... just the blocks are different)... but i'm not 100% sure on that one.... but in any case, i'm using my 4a-fe ecu and wiring on a 4a-ge..... just need to lengthen a couple wires

and i would suggest since you're spending all the money as it is and spending the time for the rebuild.... go with something other than a US 4a-ge ecu.... go with something that is map based... just IMO
