Guest joey_2315 Posted July 2, 2015 Share Posted July 2, 2015 Hey guys, need some help with the ecu wiring. Details are: 1999 SZ-R 6 speed manual -It is running a 5 speed ECU with a non-vvti engine (i bought the car like that ages ago) -A02B diff OTHER CAR 1993 TT Auto 4 speed automatic (picked up for cheap) -stock ecu -A02A diff Im trying to swap both engines and get both cars running. I need some help in getting the tt auto ecu to work with my manual as well as my na manual ecu to work with the auto car. What are the specific mods? Would it be easier to get an ecu suited for that engine and transmission? Thanks!! Quote Link to comment Share on other sites More sharing options...
masterfett Posted July 2, 2015 Share Posted July 2, 2015 unless im missing something here, the manual ecu wont work with the auto box, but surely you have just swapped the TT engine and kept the 6 speed box in place? if not you are mad! auto ecu will work with a manual box manual ecu will not work with autobox Quote Link to comment Share on other sites More sharing options...
Guest joey_2315 Posted July 2, 2015 Share Posted July 2, 2015 nah im planning on keeping 6 speed with tt haha ok what about the manual wiring harness, would that work with an auto ecu then? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted July 2, 2015 Share Posted July 2, 2015 You can run a manual car with an auto ECU, but not the other way round. Quote Link to comment Share on other sites More sharing options...
masterfett Posted July 2, 2015 Share Posted July 2, 2015 nah im planning on keeping 6 speed with tt haha ok what about the manual wiring harness, would that work with an auto ecu then? but if you are just taking the engine out of the auto TT and dropping it in the na.. i dont quite understand why you are swapping ecu's at all!

Guest joey_2315 Posted July 2, 2015 Share Posted July 2, 2015 I'm planning on getting both cars running, so I've decided to get an NA auto ecu with wiring loom as well as an a340 NA transmission to get the NA car working. That should be fine yea? Quote Link to comment Share on other sites More sharing options...
