HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

I have used a Fitech on another car and will not do it again. It ran ok. Idled sometimes ok, sometimes not. Wouldn't learn very fast. Was extremely rich most of the time, to the point of gas fouling plugs. Finally got it running pretty well, but found that the same car with a carb was faster and ran better.

As far as the FItech LS intake setup, as of a few weeks ago, it's still not available.

I have also used Holley HP Sniper. Was a little more money, but way better system. Tunes quickly and runs great.

But, for our applications, I'll stick with stock ecu and HP tuners.

Oh man, wish I had read this earlier. I was back and forth between Holley and FAST and recently canceled orders for injectors and an LS3 intake to go with the FiTech kit. I have a re-worked L92 that I'm purchasing from a guy a met at the PRI show, who is going to run it on their engine dyno at their facility in MI.

Soo...for primarily track time, do you think I should pivot once again to Holley or FAST? I also had considered this company here in Cincinnati called Performance Electronics. It's probably a little over the top but they are SUPER helpful and would handle the install and tune in their facility. Everything is custom, big race team type stuff. However, it's about double the Holley system in price.

Would love some thoughts from some of the more experienced DE guys!

In all honesty, I would stick with the GM ecu and a good standalone harness. They are very good, with lots of tune ability. For a few hundred dollars, you get a system that is virtually bulletproof.

I've never heard of Performance Electronics, but after looking at their website, you would pay a lot more money for the same thing you get with GM stuff. Plus the fact that you have to build the wire harness from their kit, and it appears to require external components to run the coil packs. No thanks.

As far as DE and racing goes, I've built several cars for that using the GM ecu. Never had a single problem.

But, if you are set on using an aftermarket system, then definitely use Holley.

im of the same mind, unless your going for crazy horsepower and making changes all the time, the stock gm system works fine. in fact, you will always get better cold start, driveability, and far better diagnostics out of a stock ecm than you will a stand alone system. gm puts millions upon millions developing them, it makes it hard to beat.

imo the only downside to the stock system is the cost of hp tuners. $500 for the basic, and $650 for the pro, and i myself recommend the pro so you can easily input your wideband o2. but you can look at the cost a little different, its $250 for the pro cable and you get $400 in credits with it, so you can tune 4 vehicles. typically the cables dont lose their value, most of the time they sell used for $200 + the unused credits. so if you tune 2 vehicles you have $200 in credits. and you always think you will tune more than your one car, thats what i figured when i bought my hp tuners cable years ago, now ive used 40 credits.

Thanks, guys. I've been really torn about this and I think what you're saying makes sense. I might go with a hybrid approach (no pun intended) and as if Performance Electronics would install and tune a stock GM ECU.

I'm still considering fitech
Reason
Gradual performance upgrades
Cam
Maybe blower or turbo

Otherwise I'm paying each time for dyno our mail order changes

I still need hp tuners

It adds up fast

Just fair warning. Once you install a bigger cam, the Fitech really gets lost.

Do you currently have a GM ecu and harness? If not, contact Kent at Texas Performance Concepts. He can get you a good deal on a package with a good base tune in the ecu.

If you have a GM ecu now, there are several places you can send it to and get a base tune loaded. The place you will be using for your tuning should be able to give you a base tune as well.
