Re: Project Overhaul Little C

Any specific reason you guys went with 65lbs injectors, instead of 50lbs? Since it's only going to have a 20G.

Re: Project Overhaul Little C

So far the 65's have proven to be great injectors and I would even say right now more consistant than the 50's.

Also providing you get the right 65's, no ECM upgrades are needed and we have a code59 base chip for them already. Just gives Paul plenty of room to grow.

Yesterday kicked our ass with fuel rails. Trans is all in, PCS controller is awake now. Today gotta finish the fuel issues, hopefully start it up and trans will work. I hope.

Along with running to store 3 times or more for parts just slowed up WAY down.

I am leaving for Tacoma shortly. I have no idea what time I am supposed to show up; hopefully I can still help somewhere. It sounds like you are almost done!

Re: Project Overhaul Little C

Is it running?

Re: Project Overhaul Little C

Syty's never end, always something. Suspension got put on back burner for another day.

Truck runs, trans is in, now gotta get the controller to work, see RPM. DP in also.

Tomorrows task is test drive.

Thanks for everybody that showed up today, it was fun.

Re: Project Overhaul Little C

For those of you that didn't go, it was a blast. Thanx for the food Jeff, it was a great getting to meet you, Paul, and some of the other NWSTP memebers. Tell your parents thanx for letting us use their stuff, pretty cool place they have.

Re: Project Overhaul Little C

Paul just left driving the truck home.

The new controller seems to be working perfect, the issue we had last night went away this morning with a fresh upload.

He still has a dash to assemble, but we did get done everything we planned minus the fuel rails (long story) and suspension. I guess that wasn't too bad. Paul and I were dragging today and didn't have much energy but it did feel good to see it move and shift like it should.

1st time that truck has seen a TCC lockup in many many years.

Re: Project Overhaul Little C

I really appreciate all the help Jeff gave me with the mods, especially the 4L80e. The thing drives like a dream now. No more slipping trans. If it wasn't for Jeff's help, there was no way I was gonna get the 80e in there. He made it look like butter. Slide right in. It was actually easier to install than taking out the 700r$... LOL I owe you big time Jeff.

It was nice to meet some new faces that showed up. Hopefully we can meet up again Roy. It was fun BSing late into the night. Helped us all relax from the 3 days of broken knuckles.

Thanks everyone that showed up and helped. Especially Roland Black :tup: . He just started to put the DP and the Intercooler back on when we were eating. Sorry for the gasoline bath when we tried to fix the leaking -6 AN line. Without him I think we would have ran out of steam and still be putting it back together today.

Now I have a bunch of bugs to work out. Found out my turbo has too much front play and I need it rebuilt. Once that is done it should be back on the street. Can't wait.

Thanks again Jeff.... just let me know when you need some help and I will fly out.

That would be soon. Jeff needs to get his damn Typhoon done soon. We should all plan a weekend, fly into town and wrench on Jeff's shit.

Re: Project Overhaul Little C

I'll get some pictures posted of the mods soon. I don't think I will be able to be Marty's quantity of pictures but I will give it a try.

All I have to say is hands down, the 4L80e is the best mod I ever did to either of the Typhoons I have owned. Shifts way better than my 700r4 ever did. No hard down shifts when I get on the gas. Quick and smooth shifts when getting on it. Of course you can change that if you want with the software for the 80e controller. Still way better than the 700r4 and I don't have to worry about blowing up the tranny anymore.

Also the PCS Trans controller is nice. I am glad I went with that over the TCI unit. It was the easiest thing to wire up using their harness. Plug in the GM 4L80e connector on the trans, the TISS & TOSS connectors on the trany then just run 1 wire to the MAP, Coolant, RPM, TPS and 1 common sensor ground wire on the ECM. Hook up Power and Gorund of course and you are done. There is a brake light wire you can hook up so it will unlock the TCC when you get on the brake but I will run that at a later time. There are a bunch of other inputs and outputs you can do for manual shifting, read other sensors, put the unit in Dyno mode, Snow Mode, use another cal for differnt shifting, etc. It has a lot more it can do that I ended up using. I really like the software compared to the TCI. Plus it will use TPS and MAP to control line pressure and shifting compared to just TPS that the TCI unit uses. I still need to tinker with it some more to understand it all. Check out www.transmissioncontroller.com if you are interested. Also their tech said TCI is switching form FAST to the PCS unit for their Controller. Hence why the price is going up on the TCI unit. But I don't know when that is happening or if it is accurate.

Re: Project Overhaul Little C

That is true. The TCI unit will become a modified PCS unit. Biggest problem is the software. Extrememely complicated compared to the TCI. TCI hence is doing a trans specific setup with the PCS style along with their own software. And the price will be much higher than the current unit from TCI. It'll basically look like a red PCS unit but the hardware inside will be slightly different and the software will be completely different. Eventually everyone will realize the 4L80e is the way to go. I'm glad David talked me into making something that worked.

Re: Project Overhaul Little C

Didn't seem that complicated. I only breifly looked at a TCI unit so I wouldn't know how much different they are.

I used their premade wiring harness and then the 4L80e definition file for their harness. it was pretty much plug 'n play except for the couple of wires we had to run to the ECM. The default config was pretty good starting point. Jeff and I didn't have to play with the default config much after that.

Thanks again George for your work to get the conversion figured out. The 4L80e is the only way to go. I got mine from Jeff back when they were trying to figure out how to put it in Jermey's Sy. I should have done it a long time ago.

Re: Project Overhaul Little C

I started with the PCS unit. There were no base programs, nothing at the time. Controller was $650 + $150 for the harness(back then) and no one was able to help hook it in. I offered up wiring schematics and everything but no one had a clue. TCI is plug and play. I hope they carry that plug and play over. If you took the PCS with no base program and the TCI with 5 wire hookup and easily programmable features, it was a no brainer. Like I said, hopefully TCI keeps it plug and play easy.

Re: Project Overhaul Little C

Maybe I'm a glutton for punishment, but I still don't think that the GM ECM is a bad choice either. Seeing both Darons and Jeremys truck run on it, I think it has all if not MORE features than the current TCI controller. There is ZERO comparison with the plug and play TCI harness though. Using a GM ECM is definately a "geek" way of doing it, and as such requires a ton more hands on wiring. As well as some decifering through tunerpro to get a good definition file.

In the end I don't care what you use to control it, going 80E is not a decision I think anyone will ever regret.

Glad to hear you got your truck up/running, and even locking the TC again Paul!!!!!

I saw your post on there from back in Sept 2004. The definition file has a release date of Aug 2004. I think when you tried it, the problems you ran into was just a product of being bleeding edge when you tried it and you probably got the univeral 4l80e harness. Which looks like you have to run wires to everything yourself. That would be a nightmare.

Lets just say their documentation is written more for the person who is making their own harness. It wasn't written for the plug 'n play crowd so you can get confused looking at it. Also 2.0 of their software has been in beta for over 2 years.

Now they have 2 other harnesses for the 4L80e. 91-92 and 93+. The harness pretty much plugs into the trans now and you just connect a couple of wires at the ECM just like the TCI. We initially had a problem with the unit not seeing RPM even though we were connected to the D9 pin like on the TCI unit. We tried a different definition file from their site and then it worked. So it wasn't the easiest thing to get going since their documention was lacking. If you want I can take some pics and do a write up so if you ever do one, it will be easy. I am sure it will be different than the new TCI unit.

You are a glutton. The GM ecm is really not that hard once the wiring is figured out. Those like Jeff that have gone before and figured out what goes where made things much more plug and play like. I may even get the Tahoe ecm its own Ostrich so I dont have to burn chips to change tranny parameters. My 4l80e is actually working pretty damn good now that I got the wiring right. I got TC lockup and all. All I really need to do now is just fine tuning when lockup occurs and when it releases. I may up the shift points in the future to better match my cam...

Re: Project Overhaul Little C

Initially I was going to run the GM ECM since I helped Jeff get the one he set up on Jeremy's working. When he was doing the GM ECM, I was on the phone with him looking at diagrams, reading thru the GM ECM code hac I had, etc. to figure out why it wouldn't shift. Took us a while to find the correct code mask to even run the GM ECM we were using. $31 didn't work, $85 didn't work, $OD was for the 60e, and finally $OE worked. Problem is, the hours we both spent on the $31 XDF were lost since we didn't have a very good code hac for $OE. But the TunerCat definition translated rather well to Tunerpro and gave us what was needed to get the it working. The big thing came down to Jeff using the VSS off his Tahoe so the tranny would see the correct MPH. Then it shifted.

I decided to do the PCS Controller on Jeff's suggestion. My tranny core was in good shape so the rebuilt wasn't as much as I had budgeted for. I decided to get the PCS controller since I had money left over from the budget.

It was really easy to hook up. We had the wires ran in 15 mins. After getting the controller installed. Jeff said "This is the controller to go with. Shit.. if we were hooking the GM ECM up, we would still be running wires and trying to track down a VSS from a 95 Tahoe. This is the controller I am gonna run."

The only problem we had with it was it wouldnt' see RPM when we first hooked it up. We had worked on my Ty 10 hours that day so we were pretty tired and went to bed. The next day we got up and had it working within 30 mins. The problem ended up being I uploaded the wrong 4L80e Calibration file the night before. Once I get the one labled 4L80E Base 7.20.2004 w-pcs-harness and used it, everything was working.

Either solution would have worked. I am a tinkerer so normally I would have done the GM ECM. I am gald we did the PCS because it cut down on the install time. We were pretty burned out by the end of the 3rd day. On the 4th day when we got up, once it ran and shifted, I put the dash in and drove it home.

Re: Project Overhaul Little C

Sometimes that's what it takes. Just walk away from it for a few hours or do something else completely. Come back with a blank slate and "poof", why didn't I see that before?

Yep. I was "bugsdad" on the PCS forum. They never did understand even after sending many emails. I bet I had 10 pages of schematics showing their harness, syty harness, then I worked them together, looked at speed sensor input vs out VSS output, DRAC output, the way their unit needed a signal based on programming, etc. Never could get that done. Hopefully some of the information I sent them led to the better program and design for the harness. The kick in the butt is you can run anything, a fork lift even with that controller, if you don't have a base to work with, it's REALLY tough.
So when are we gonna see a wire schematic and "how to" on the PCS?

Re: Project Overhaul Little C

I'll make one soon. Have some bugs to work out of everything before I can drive it again. (not trans related, I sent the turbo in to get rebuilt) Just want to make sure everything is good before I post it. Don't want to put bad info out there.
