Disconnected sensors and Reading the ECU.

Unread postby Stang95 » Wed Oct 10, 2018 5:16 pm

I am wondering if: Does the unmodified ECU "learn" and store how it's been running for me to Read what's been stored ?

When i read the ECU my hi slope and low slope read the same.
My MAF minimum says : 2.9498 MAF max says: 3.8914 ....That isn't far apart at all. The MAF and IAT has been disconnected.
Car runs good and still spins tires But DEFINITELY runs rich.

Or do i just have the wrong .bin / .adx combo ?

Running no MAF or IAT. Made an EGR gasket with a hole in it so the vehicle idles without dying until tuned.

i REEEAAAALLY want to learn what each thing on the Tuning Softwares mean.

sounds like your not getting a good read. Most likely a dirty j3 port. Be sure to remove all the plastic off the j3 port terminals. If you have a sn95 you do not need to read the stock tune just simply write a modified tune to it. Key has to be on to read the stock tune though.

the maf and iat are both critical inputs. Either one missing will eventually cause a blown engine.
