yup, headed to fresno performance today to get the mach dyno-tuned. before heading there, i knew the mach was in a bit of a bad shape... but didn't know how bad it was until i took it there. now, remember... i ran a 13.567 @ 109 with my mach in horrible condition
- misfiring
- pinging
- bad tires
- bad tune
- not running on all 8
- bad plugs
- bad knock sensor taking away 8 degrees of timing
i don't know how, but i did. i also made 274 horsepower with all of that going on.
today, when nate put it on the dyno, he discovered the bolded and fixed all of them (mostly due to my plugs), except the red. now, today wasn't the best of all days to try and do dyno pulls... last pull it was 105* and intake temps were about 130*... but even though, my mach put up some good numbers for an auto. better yet, it runs a HELLUVA lot better, so i can only speculate how that will translate to the track... seeing as i also now have a decent set of tires to run with.
to explain my final numbers, nate basically turned my knock sensors off and tuned my car the way he would a cobra (no knock sensors, 32v motor). the tune he gave me was on the very safe side. i had one pull where i made 293 hp and 316 lb/tq. but that was an unsafe tune (detonation).
i had the option of getting my knock sensor fixed, but as i'm low on funds right now, i trusted nate's ability to tune cars with no knock sensors (being he tuned his own cobra and other cars without knock sensors). final numbers / dyno sheet:
287.01 hp / 307.69 tq on a safe tune with no misfire, pinging, and most importantly no knocking. :rofl: that was important to me as he did turn my knock sensors off. he also firmed up my shift pressure a bit and changed my shift point to 6300rpms. thank you, now the mach stays in the power curve more and doesn't short shift me (did on old tune), so i now have some top end pull.
all in all, it was a good day. i hit the 290 mark like i wanted to, but not safely. on a cooler day (read: not 105*), i probably could pull off a 29xhp dyno pull. but to fix nearly everything that was wrong with my mach and have it still pull that strong on such a bleh day... awesome. :rock:
