    6.0 turbo build advice

    My turbo lm7 had higher compression, and I seen no evidence of knock. Sometimes there was a slight bit but only in reverse at low speed, downpipe touching a seam on the cab. I really just want to play it safe. No e85 anywhere near me, only 93. I am ordering the xmax soon though. Looking forward...

    6.0 turbo build advice

    Thanks for the info. Its std bore and stroke. After reading a bit, looks like I may benefit from a new cam. The tss I have is 218/224 .600/.600 113+3lsa. I figure I could repurpose it for the 6.0 swap? It has 317 heads, and 9.5:1 compression and im on 93 octane pump gas. Should I be looking to...

    6.0 turbo build advice

    I'm in Powell River so that's super close. Let me know if you hear of anyone. Would love to have it tuned on a dyno. I don't mind doing the logs and revisions but it's pretty time consuming.

    6.0 turbo build advice

    I'm on the coast of bc. I will look them up for sure. I searched long and hard for a tuner from the north.

    6.0 turbo build advice

    Greetings from Canada. Looking for some tips on a street build if anyone has personal experience. I have a 6.0 lq4 that I'm about to send out to machine shop for balancing and cam bearings. My goal is to build something as close to 4 digits as I can without sacrificing streetability for my 97...

    Passenger firewall plug pinout

    Thank you. I did find 2 grounds and a red positive for the heater motor. There was also a module for the fuel gauge. One for tcc lockup and another for ground to instrument cluster. Long story short, I grounded the 2 negatives behind the glove box, ran the power wire across inside the cab and...

    Passenger firewall plug pinout

    I'm a little embarrassed to admit that I can't find the info I am looking for in the manuals. If there is anyone who can let me know which colors are what I would send over a digital case of beer for their hassle. The wires are cut on the engine side with enough there to graft on new wires.

    Passenger firewall plug pinout

    Its a 98 c1500 reg cab shortbox. Was 4.3 manual. Now its 5.3, 4l80 14 bolt. I will see if I can navigate through the manuals. Thanks.

    Passenger firewall plug pinout

    Onto another issue.. and looking for some much appreciated help. I was quite eager and foolishly cut the passenger through firewall harness and removed it from my harness when ditching the 4.3 for the 5.3 swap. I have been messing about with grafting a stand alone harness ever since. The truck...

    4l80e pcm command requirements

    Figured I would let you fellas know what was up. Finally got the trans working fine today. It was a bit of a dick around on my behalf with the wiring. I had swapped the pins in the trans connecter to change from 60e to 80e. It didn't work the first time because I wasn't getting power to the pcm...

    Ls swap oil pressure gauge

    Started the truck tonight, the 03 5.3 oil pressure sender hooked to the gauge works fine as is. No need for any modification. Now... to get the tach working.

    Ls swap oil pressure gauge

    You are correct on this. My factory pressure sender on the 4.3 that came out of tye truck had 3 wires. I just didn't understand why people were saying I needed the adapter as this one looks like it threads right in. If I don't need the 2 wires for tye fuel pump I will try to use the LS one wire...

    Ls swap oil pressure gauge

    here is the beginnings to trying to get some of the factory gauges back operational. The oil pressure sensor in the pic is what I removed from the gen 3 ls, it has only 1 pin. It looks identical to the parts store stock replacement for my 97. I bought the adapter to ⅛npt but neither of those...

    4l80e pcm command requirements

    Thanks for the reply. My pcm is an 0411 I believe. I do not have the brake switch wired to the pcm, this is what I am trying to determine. Is that only to unlock the converter or would it hinder upshifts aswell? The harness is a stand alone harness. Like I said previously I can command 4th gear...

    4l80e pcm command requirements

    Is there a reason why I can't command tcc lockup with hp tuners? Sounds like Nothing happens, and no change of voltage or grounds on the plug

    4l80e pcm command requirements

    4l80e is used, suppose to have been tested and good from a 2500 van early 2000, but there is no guarantee. My truck is a 1997 c1500 rcsb. Had a 4.3 manual. Its now lm7, standalone harness, 4l80e and a 14bsf.

    Thanks! I did so.

    4l80e pcm command requirements

    Thanks to everyone who always takes a minute to help people like myself stumped. It sure gets frustrating when all the problems happen simultaneously. I need to start with one and see it through. my 4l80e won't shift to fourth unless commanded by hptuners. I cannot command any function for the...

    Thanks for the reply. Appreciate it. This truck has been beating me up a bit. I will get after the downloads.

    C100 pinout

    The world is not messed up enough to say that this firewall plug in the diagram is what I have right?! This wiring is killing me. Still no tach after 1k resistor. No fuel gauge, no temp gauge and no oil psi, volts say less than 9, multimeter shows 13.5v. Fml. If anyone has the proper firewall...
