Engine management

[procket2_8]

What engine management do you guys run or recommend?

Also where should I look for head gaskets, Gm doesnt produce them anymore, the part number is discontinued...We needed to pull the heads, l;ost compression in one cylinder, ended up having bent valves and a blown HG

Better than replacing the JE pistons that are in there.

What turbos have you guys had the best luck with, I personally like Garrett, but if precision is a nice replacement(bolt in) Id go with that. Im doing a air to air setup as well due to the fact that crappy little air-water thing is garbage and may have caused the valves to get bent from running too lean and too hot.

Thanks!

Re: Engine management

im using the stock ecm with a Moates adapter and burning my own chips with a lot of help from this board.

As far as head gaskets go... a search will find tons of references

Re: Engine management

Cometic or SCE for gaskets. R.P.M. and Waller here on the board have some real nice mid to mid/hi H.P. turbo upgrades depending on how far you want to go. Precision or Turbonetics for the higher H.P. units (IMO) and hang tight for a while and Code 59 will be available for tuning.
Just my :2cents:

I run a Big Stuff3 Unit on my truck tuned by Harry Anderson (pa) Cometic gaskets on those heads and i have GT35R turbo which will put me into 10.9 range for the street. That in my Typhoon. On 13lbs of boost we run 11.9-12.0 all day on pump gas alone.

Re: Engine management

I did a search, and found a few places, but I was curious as to how dependable or the validity of them were.

Thanks for the info, anymore is appreciated! :tup:

Re: Engine management

Also: I like the idea of standalone, but i dont know if my brother is capable of dealing with issues were to arise, is there a plug and play chip?

The engine has pistons and a valve job, so Im not worried about it not being able to take more boost.

Re: Engine management

After working with the autoprom and Tuner Pro I've got no reason to change to a aftermarket ecm. Real time emulation.
I just put on a set of Cometic's from Waller. Works great! Fel-Pro dropped the ball with these engines. They make NOTHING for it.
I use FAST systems on all my GN stuff since the factory system is not as nice or fast as the Sy/Ty ECM's.
Tuning on the Moates Autoprom is just as good as a FAST if not better IMHOP.

Re: Engine management

the big stuff is probably the best interface stand alone out right now. available with a plug-n-play harness fr the syty and straight forward tuning software. has lots of cool features like integrated wide band o2, datalog, 2 step, aux imputs etc. nothing revolutionary from say the old FAST, and DFI but nonetheless it is the latest system with plu-g-play wiring harness. the nice thing about the standalone is the ease of tuning. Sure there are excellent capabilities with the stock ecm, but it will take you 10x as long to dial in a truck with stock computer as opposed to a good stand alone.

As for the head gaskets, we stock the victor renz which is a stock oem headgasket. They work very well. The cometics are bulletproof, but bear in mind if your tuneup is off a piston is more likely to fail then these headgaskets. in either case we have probably 10-20 sets of each in stock.

Hey Mike,
I got my Big Stuff3 From you works great. Few Questions Plug & Play harness How much$, How much for the Big Stuff3 Computer, and also on the system a wire comes out of ECM says 2 step how do i hook that up to work. I have a friend who may switch over to a Big Stuff unit and i want pricing from you for the harness and ecm
Thanks Ralph

I have JE pistons in my engine so having a better headgasket is good. Is there any other weak links in this engine, besides the heads and pistons? What kind of boost can on run on just pistons safely?

Thanks btw ill be talkin to you soon.

How about the SCE head gaskets? I was told as good if not better than Cometics and don't require special deck finishing. Do you have these or have used them and if so what do you think. If you recommend them, please PM me the cost of a complete head set with Felpro intake gaskets to the do the Vortec swap. I also need a replacement diaphram and o-rings for my AFPR. Throw that in also.


Thanks!

Re: Engine management

The aftermarket ECM's are great... but there's even more adjustability if your willing to spend some time learning with Tuner Pro and Auto Prom. There's nothing a aftermarket can do that the stock ECM with AP and Tuner Pro Can't do. Data log, Wide band O2 and I had 300.00 in the all the stuff from Moates to do it. Aftermarket widebands are 130.00 AEM or others will work with Code 59.

I have Cometic's on the wife's Typhoon. 4.3's are not like GN's. They don't pop headgaskets they waste the bottom end or destroy the pistons. Lots of fun. Just went through that.

Good luck with your decision.. you'll be happy either way.
