Title: noob here - need to know if i'm the right place? Post by: hummel on April 03, 2018, 01:47:34 PM Hey Gents,
A brand new noob have arrive. I really want to understand more about the ECU, specially the ME7, because I believe that's the one i have with my R32 engine. Just to get started i downloaded the Nefmoto ECU flasher, and first job for me is to bench flash my ECU, when i get a prober DC supply and the rest of my wiring. I read the S4 Wiki and freaked out a bit :o Thats alot to handle at my first day at school :) And now i have some questions for you guys... Probadly stupied. Facts: R32 BUB Engine with all stock engine harness and sensors. Golf mk1 car, no ABS, no Cat, no CAN-BUS, nu steering colum unit, no airbag, no IMMB, no nothing. I want to know if I can make my R32 run without all these thing to communicate with, is it "just" a flash of the ECU and a rewrite of the map (I know it not "just" but trying to understand it) or does it need a CAN connection from something to function? I believe the engine can run without following stuff as well: SAI EVAP Exhaust flap Clutch positioning Brake positioning Rear O2 sensor (Since no cat) these things will also have to be deleted in the map. I know is a big job to learn to do this, but I have alot of spare time and I believe I can use this knowledge, so i want to learn it. But if it is impossible to get it to work with the ME7, I will not try. Can anyone tell me if i'm all wrong? /Tommy Title: Re: noob here - need to know if i'm the right place?

Not sure what you mean by "a rewrite of the map". There are literally thousands of maps. Incidentally, it is unlikely you'll get much gains from a N/A motor.

"A rewrite of the map" Was my way of saying that think i need to let the ECU know that all the other system aren't mounted, or can i just leave the CAN wires unplugged, the SAI unplugged, the EVAP unplugged etc. and then the ECU will still work like normal ? I don't look for gains, but just a engine thats runs like it would in it original car. Title: Re: noob here - need to know if i'm the right place? Post by: _nameless on April 04, 2018, 05:04:09 AM ;D
Title: Re: noob here - need to know if i'm the right place? Post by: _nameless on April 04, 2018, 05:06:23 AM Youll need a immo offed eeprom first off if you plan on swapping the engine into a different car otherwise youll have a very heavy paper weight . If you want to remove the emissions related hardware youll need to figure out how to disable the emissions testing and how to code out the hardware that will be removed. No the engine will NOT run right without the emissions hardware coded out and hardware removed. Thats about all the help youre gunna get so best off start reading Title: Re: noob here - need to know if i'm the right place? Post by: hummel on April 04, 2018, 05:51:32 AM thank you guys.
