I wanted to get a data log, so I decided to bring the camera along so here are a couple in cab vids. I'll forewarn you though, I didn't get on it that much though, so if you get to the end and thought it was boring I apologize in advance. This definitely isn't a "Mexico" vid

Couple other things, it seemed way more exciting from the driver's seat than it does on video, wish you guys could get the same experience, cause it just screams over 3000 RPM.

You'll have to forgive the sniffles, my co-pilot and videographer is battling a cold

Anyways, enjoy!

At 2:02 i was all smiles. Badass dude.

 

Thanks dude, it's really hard to resist giving it gas underneath bridges and underpasses now haha.

Do you have the same username over on gmfs by chance?

 

how the eff did i miss this build thread. bad *** truck homie. I know what im doing to my truck once im off vacation lol

 

Thanks bud, I highly recommend it!!!!

 

Small update; I've been teaching myself EFILive for the last couple weeks, and getting better at reading datlogs and pulling info out of them, so I'm going to start posting some numbers by date, and hopefully start incrementally improving them.

I put hoseclamps on the vac lines for the PCV system, siliconed around the catch can fittings and replaced the regular oil filler cap with a breather to eliminate the connection between the clean air input on the pass. valve cover and intake tube.

Drove around last night but didn't datalog, just watched the aeroforce gauge. Vac was up by 1-2 inHG, and it felt like it drove better the first few mins but the p0171/p0174 lean codes still popped up, and the frequency of "service stabilitrack" messages on the DIC seemed to increase (they come on for a few seconds at low throttle input, then disappear when more throttle is given).

So tonight and this weekend I'm gonna do some datalogging and hopefully get going in the right direction.

Also throwing around the idea of going with an SD tune just to satisfy my curiosity

 

have any EFI tuning classes around you? thinking i might take some sometime to learn more and maybe do my own tuning. or at least maybe work at a performance shop with that and my engineering degree.

 

Good to see you going with it. Truck sounds real good! You running through full exhaust in the video?

 

Doubt there's anything 'local' but I should look into that. I've thought about going to one of the tuning seminars that FAST has, probably wouldn't help specifically with GM e38 PCMs, but the theory of VE tuning would be nice to add to the knowledge pool.

Thanks, and yes full exhaust.

*EDIT: Just read your sig after posting, seen you have the Roush 1.9, so just thought I'd ask, after putting it all together how were your fuel trims?

 

i have absolutely no idea haha. justin sent me a base tune and i put about 150 miles on the truck before taking it back off the road to do the trans and converter. so really its not totally tuned and i dont know any of the specifics of it anyway sorry
