Hey y'all, I just bought my first dsm, its a 91 Galant VR4 (929/2000). It has Slowboy stage 2 block, Slowboy head, 58mm FP red, 1200cc FIC injectors, ECMLink v3 and a bunch of mods. Unfortunately there is some front end damage from a previous owner and after that I think she may have been neglected a bit.
When I got her she was hitting fuel cut around 12 psi. I installed a AEM truboost and it ran a little bit better and wasn't hitting fuel cut as often. After looking at the tune it was set to hit fuel cut at 11 psi. I'm pretty sure its running 14.5 pound waste gate spring so I hit fuel cut anytime I floor it. The engine can definitely handle 14.5 psi so I'm not sure why the fuel cut was set at 11, any ideas?
I datalogged a 5 min drive and everything looks pretty good but my timing is jumping around a lot, I'm not that familiar with DSMs so I don't know why this is happening, I know the O2 sensor is bad which is making it run very rich but I don't feel like that should affect timing.
I have the data log but it is quite long, how do I shorten it? Also how do I save the current tune? I want to edit the tune but make sure I can go back to the old one if I can't figure something out. Lastly I want to get new coil packs because it is COP but I can't find any ones that look like good quality. What brands do y'all use?
I am very excited to join the community and would appreciate any help I can get.
