Got a chance to work on the car yesterday and did a few things:
1. Swapped out the MSD distributor for one that
@a91what Steve so graciously let me borrow. I forgot that he also gave me a TFI module to try (it was in my trunk
) so I used the module from my old stock distributor. I also used the cap and rotor from the MSD, let me know if you think I should be pick up non-MSD ones or if that shouldn't matter.
2. Cut my plug wires to length to alleviate the rat's nest that was previously there.
3. Trimmed and mounted the Ranger front air dam that
@stanglx2002 Kurtis hooked me up with from Amazon.
4. Reset base timing and took datalogs of cold start and 2 drives, the first with me driving, and the 2nd with my buddy Kirk driving while I watched the laptop.
At first it appeared that the stock distributor helped with the WOT hesitation around 4000 rpms, and looking at the datalogs a few of those pulls look pretty smooth and linear. Especially with Kirk driving and me just listening and watching though, I think I noticed some hesitation still. I'm wondering if it has to do with engine load being higher and that's when the problem occurs...
I did not change the tune at all from the latest 10.0.0 version as to not introduce any new variables but have attached it anyway along with the cold start log, and logs from the 2 drives.
The new air dam seemed to keep the temps lower by the way, but on the 2nd drive it seemed to help less than the first one so I'm glad I've ordered the Mark VIII fan and it should be here Wednesday so hopefully with that and the new air dam my temps will be much better
Last thing are plug pictures pulled right after finishing the 2nd drive. I had Kirk do one last 2nd gear WOT pull right before we parked to hopefully have the plug be as "readable" as possible. Someone correct me if I'm wrong, but I've read it's best to look at them immediately after doing a pull/run otherwise they might get "cleaned off" and not be useful for diagnosing WOT issues.
Thanks as always and I hope everybody had a great weekend!
