WAR chip installed, but no start!
« on: October 21, 2014, 11:56:28 AM »

* For later refference:
95 325is, 413 ecu, S52 swap, obd1 intake manifold, 3.5" CAI(for big maf conversion in a few weeks), stock obd1 MAF, obd2 exhaust manifolds, catless single 3" exhaust. The only part of the wiring harness converted was from the obd 1 (2) coolant temps sensors to the all-in-one obd2 coolant temp sensor...
I saw a recent thread with what appears to be the same problem  my car is having... I first had a laptop compatability issue with not reconizing the software, got it sorted out, uploaded these tunes: (1)S50 performance, (2)S50 performance (for same tune with launch control activated), (3) S52 21#inj 3.5" MAF (for big maf conversion in a few weeks), (4) S50 val. tune. Started the car and it crack right up!!! I waited 5-10 minutes to warm up before touching anything. Got in the car to back it out of the garage, blipped the throttle. It died and would not restart. It seemed to be pig rich. I tried selecting other maps, but same thing. no start.  :(. I read the maps off the chip and showed to be correct, but then laptop stopped reconizing the software again...) Attempted reinstalling the software, no go. My neighbor is an IT guy so I let him look at the issue. He recommended a different laptop at this point due to he thinks that the XP program on that machine was having issues connecting/running the program, even after using the on line file I found on the forums... So laptop number 2 in place. I tried downloading the software again, success! It reconized and uploaded and down loaded fine, BUT still same problem. Cracks and cracks with no start. I installed the same tunes as before.

Then I tried straight S50 stock tune, straight S50 perfomance on all 4 tunes. No go. I reinstalled my stock chip and it runs great (besides being rich from bigger injectors over stock.) I had the shop that installed the S52 look over the car and states that everything looks fine. No hard codes stored. when maf or o2 unpluged, check engine light would cycle on correctly. So back to War chip... I then tried installing the M50 stock tune on to the chip thinking maybe this would work. Same thing. just cracks and cracks with no start. Last tune I think I tried last night was S50 performance on all 4 tunes, no go...

Any suggestions?

Would the EWS be causing this?

Ok, out of just being curious and desperate, lol, I figiured it out. I answered my own  question with a little test. My car is equipted with EWS, I disabled it, plugged in the WAR chip and WALLA! IT RUNS!!!! No one has mentioned that EWS would be a factor to consider with this chip, but it made since because other tuning companies would offer the option to disable it on there chip during the order process, but I did not see it listed when order the WAR chip. So, if you run into this on future builds, save your self a week of head scratching and cursing and disable the EWS. There are write ups and videos showing how to perform this.... Now on to tuning!
