So here we go!
I got down to the shop for a good part of the day Sunday with my buddy and we made a lot of progress on the car. We got the newly fixed A5 transmission installed again and it was a bit more work than normal because of the Stiffler's spider braces and exhaust parts that had to come out with the transmission but overall not too bad.
Since I had a terrible exhaust leak at the downpipe, I got some new V-band clamps from RacePartSolutions (have I mentioned the On3 ones are garbage?) and some steel exhaust gaskets and used them when reinstalling the exhaust pieces.
Once back together, I test drove the car down the road and back and the noise in 1st gear was gone as well as the exhaust leak! Thank you sweet baby Jesus! lol
With that out of the way and the car driveable again, I pulled the passenger fender liner and got to work on installing the slot style MAF. While I was working on that and the wiring, my buddy started working on cutting a bigger hole in the fender area to fit the air filter with 90 deg elbow to get the filter out of the main engine bay and into the fenderwell. I might do a separate post on that since I haven't seen anywhere in my google'n an On3 kit with "cold air intake"...
I think it came out really great. I'm not sure how much difference it'll make temp wise but I like the look and am thinking about making a little piece of cowling that will go around the pipe to help isolate it from the rest of the bay. What's also really nice about the "access hole" we cut is that now I should be able to get to pretty much everything in the fender well (boost control solenoid, MAF, intake piping from intercooler to throttle body) without having to pull the fender liner! WOOT!
So, with that done I finished up wiring the MAF temp signal and return wires to the factory harness and swapped the MAF and MAT pins in the ECU. When I connected tuner studio without the car running, the MAT was reading 83 so it seemed to be pretty accurate. I started the car and let it run for a bit and got worried that the MAT didn't seem to be increasing but eventually it did by about 10 or so degrees. I've attached the log here for you guys to let me know if that seems right or if there's something I need to do with the sensor/wiring/calibration.
I'm so used to the MAT being both very high and increasing quickly that seeing it pretty steady at around 85-90 (idling) seemed like something was wrong. I'm hoping that it's correct though and a good sign since it's now in a MUCH better location than before! Big thanks to
@a91what and
@stanglx2002 for helping me brainstorm and realize that I could use my MAF to get the temp
I think that's pretty much it for this update... I'm going on vacation Friday through next week (Asheville and N Georgia) so just been so busy trying to get things in order at work so they don't have to bug me while I'm away haha. One can hope anyway
As always, let me know what you guys think and if there's anything you think I should address. Thanks!
