Flow rate of injectors on GM FI system + TEC3 Proj
Discussion
Does anyone know what the lb/hr flow rate of the injectors is on the GM FI?
I have decided to fit a Electromotive TEC3 ECU on my 88 (replace the k-tronic) so I have to fit a new injection system (need electronic injectors). I intend to document the project (before/after HP, pictures etc.) so I can post it on here (and perhaps LEW??) in case anyone else is interested. I am told that the TEC3 will give another 40 - 75 HP (I'll believe that when I see it of course)
I'll probably be needing a new gearbox next

Do you have access to a wideband O2 sensor?
It gives you control over everything (just about): boost, timing advance/retard, etc. etc. As I said, "I'll believe it when I see it" on the HP thing. The main reason I am doing this is not for more power, but just because the K-tronic is a bit outdated and not too easy to keep perfectly tuned, plus I am pushing quite a bit more HP already than stock and I like the fact that the TEC3 keeps an eye on your engine and lets you know as soon as it sees anything amiss. I just enjoy projects like this, gives me something to do
Oh, and I found out the flow rate, just in case anyone else is interested: main injector 360 cc/min, secondary: 190 cc/min. John Welch of wcengineering.com was very helpfull with this.

I have the TEC-3 on my Tuned Port Injection 406,in an 87' Pontiac Firebird. Great system, very flexable,
but..., its a little complicated to set up( a by-product of the systems flexability), for instance, there are about 14 different parameters that have to be set up for the IAC sensor alone!
There are no safety nets built in relation to ignition timing, you can easily damage your engine with to much timing. Pay very close attention to the timing trigger set up, make sure(confirm with an old fashion timing light) that you timing at idle is what you have it set for.
Also I would suggest that you read the manual from cover to cover twice, maybe three times before even starting the install, I found that there was a little to much info to take in one go.
Best of luck with the install, keep us all posted on your progress;-)

My car is not legal because non of the original bosch equipment is on the car.
And since they now have skimatics on all 88's makes it worse.
If you get your car maped I would like to see it to compare notes.
Just incase if you have ever wondered. Your 88 should be 185hp at the wheels at 9psi of boost. Mine because I have raised the compression and the new tech system I make 197hp at the wheels with only 7 psi. This is due to brake in.

IF you haven't considered Autronic I would highly suggest doing so. I am installing a Autronic ECU on my saab & I was considering several aftermarket ECU but decided on Autronic. The biggest selling point for me is their Autotune feature. You simply rent a Autronic Analyzer & hook that into the car's ECU & the analyzer greatly reduces dyno time. Base parameters must be manually (via laptop) changed to get somewhat close to what the car requires then the autotune/analyzer does the rest.

Davesport is who I have been dealing with

Hey Guy,
I think my car will be a little more than that at the wheels (seeing as though I'm pushing around 16psi of boost, plus some other "naughty" stuff I have done)
- Fitted an intercooler a while ago and it works very well (have gauges monitoring i/c water temp, MAT, etc.). Of course I won't be needing them when I get the TEC3 in. Mark - 88 Turo

The Autronic is a good system, did quite a bit of looking around before I purchased the TEC3. I like the versatility of the mappings on the TEC3, I would rather be in control of the mappings and setup than have the fine tune thingy do it. I like to see how the system reacts down to each individual cylinder and have the capability to fine tune it to that level.

Stick with the 88
You have "The First" of the Stevens, there is something to be said about that! Even if you go to the S4 and decide to change the ECU; you will probably end up replacing most of the injector system anyway as the standard GM setup won't accomodate many mods.
I'm taking photo's and everthing so I'll be posting them when done. Probably about another 3-4 weeks.
