i plan to start a twin turbo engine buildup in the near future for my 91 trans am.. for now i would like advice on fuel/spark management. I would like a standalone unit that will replace the distributor, fuel system and all sensors.. and plan to purchase it before the buildup and install it on my nearly stock engine to practice tuning with it. i had a haltech e6k on my 87 conquest tsi with custom 4 injector setup... and would like similar control and datalogging abilities.

does anyone have any recommendations? i had an sds unit but was dissatisfied with the little nintendo style controls... very nice unit but doesnt fit my needs.

any recommendations as to distributor replacement with coil packs would be appreciated (neither of my previous management setups had distributorless ignition)

Thanks!

 

Electromotive makes a coil pack driven system that has wide band o2 capabilities.

Its called the Tec 3. Worth checking into. I know of one person who has used it and has been pleased with it.

 

I would normally consider or recommend a different type unit. But if you have had experience with it then you would be ahead of the game as far as the learning curve for a aftermarket EFI controller is concerned. Otherwise I would suggest a wide band O2 optioned either Accel gen 7 DFI or a F.A.S.T ecm

 

Motec is a good alternative too. Call them tell them what you want and they can/will custom make a system to fit your needs. UT's SAE light sprint formula racer uses it and its worked out great. Not cheap though, costed over $4800 and we went with one of the cheaper systems they offer.

 

from what ive read so far i like the tec 3


if im not using a distributor will i need some kind of a plug or is there a way i can run part of a distributor for a sensor instead of a crank trigger?

thanks for the input guys.

 

A Bank-to-Bank F.A.S.T. unit will work with an out of the box MSD distributor, a std MSD Ignigtion box (6A, 7AL, 7AL3, etc.) and when ordereded with the Wide Band Sensing option, can usually be found for around $1800-$2000. Prefer Sequential? Then get an MSD distibutor #2345 ($400), with a Cam Sync option, and SEQ with Wide Band Sensing Option goes for around $2600. Add individual cylinder control for another $600 for the ULTIMATE in tuning. I'm guessing the application is SBC or BBC based on the vehicle. Either way, the distributor fits both. I like the F.A.S.T. units because you can still use most of the of the shelf components, like the distributor, coil, and ignition box. No need to purchase coil packs, crank tiggers, trigger wheels, and so forth.

 

http://www.bennettracing.com/products/fast.html yeah i know they build up stangs

hmm.. i would probably need sequential for turbo application but if im going to have a stock tpi.. would sequential still work?

i like the way these guys think:
"We supply, at no extra charge, a program for your combination when you purchase a system. Due to the wide variety of engine combinations we build and dyno, chances are we have a program to fit your needs."

ill probably call these guys and talk to them about this setup.

 

As far as the stock TPI goes, I don't think it will be a problem. The trick is you need a cam sync sensor for running Sequential. It will fire the injectors based on the engines firing order. You only need a regular signal (Hall-Affect, magnetic, etc) for a bank-to bank set-up, which fires all injectors on each engine bank at once. I know of 1200 HP bank-to-bank set-ups, so don't rule it out just yet. I've heard really good things about Young's as well.

yeah fast certainly seems to be the way to go.. how long do these wb02's last mileage wise before they lose accuracy?

think ill go with sequential and individual cylinder control

 

That I could not answer just yet, as I current own a FAST system, but the engine isn't quite ready to be started just yet. I would think that once it's tuned correctly, it should last at least 20-30k miles. I guess it really depends on the abuse it takes. I am currently a little further along than you are, but am following the same path. Building and buying as cash permits, hoping to have something running in a year or so.

 

yeah i just bought this car 6 months ago... havent even installed my spohn sfc's yet ... theyve been sitting in my garage for 3 months.

i hope to have a turbo engine up and running within 2 years $$$$$$$!

i wanted to get the ecu first so i could practice tuning an 8 cylinder for a change.. my 87 conquest is 4cylinder

considering single turbo options also (still looking over compressor maps).. t-88 looks promising

still debating whether i should even try keeping air conditioning with this setup (i live in texas... its HOT!!)

already got the hookup with stainless tubing for my headers

buying a digital cam this weekend so i can document my progress!

 

Sounds like you've got a plan. So far I've gathered up a Dart Little "M" block with billet main caps, a Callies Magnum Plus crankshaft, Brodix 18X fully ported heads, a Brodix 18* converted-to-EFI manifold, Oliver SuperSpeedWay billet rods, and a Moroso kick-out pan for my 88 GTA. I had a nice Crane roller, but it was for a naturally apirated set-up, and thus was sold. I do have a nice of Crane Pro-Series roller lifters though to accompany a new camshaft. The fuel system is about complete as well-MangaFlow Pro-Star EFI pump and regulator, plus a huge Aeromotive -12 fuel filter, custom 16 gallon aluminum tank, Siemens 83 lb injectors, and all the braided lines to plumb the entire system. As far as the car goes, I got it back from the chassis shop about 2 years ago, and it underwent a complete round tube backhalf. 14 point cage, Kirkey seats, full dash, full interior, narrowed and braced 9-inch, custom door panels, complete stepped exhaust system, and who knows what else. Walked out $12,500 poorer, but it was well worth every penny. I'm looking to make some real power and work my way into the eights. And yes, it WILL be street driven. Didn't build it to trailer it!!!!

 

you're much further along than i am.. im shootin for streetable high 9's

sounds like you are gonna have one heck of a setup :rockon:

ill probably go with a dart block as well

wow 83lb injectors .. good for at least 1200fwhp if my calculations are correct.. and prob around 65% duty cycle!

ill prob put in a 12pt cage.. keeping full interior!

 

Yeah, I'm looking for 1200-1250HP at the flywheel. I'm going to utilize an F1R, mainly because I would prefer that everything fits nicely under the hood. The blower will support 1300 HP theoretically, so anything over 1200 HP I'll be happy with. I'm going back and forth with the A/C thing, as it's hot as hell here in Florida for all of about 3 months out of the year. But it sure is a pain to work around. The car will still have most of the power functions, and loosing the A/C would seem to move the car more away from a true streetable status. The camshaft purchase is next, probably next week or so. Everything in due time.

If your serious about ignition, investigate the eDist by FAST.
It uses the LS1 coil near plug coils.

 

They sell or MSD sells a Shaft that Goes where the distributor shaft used to...Its called an oil pump drive....Basically all it leaves is a little NUB where the distributor hole used to be...All it is is a gear that drives your oil pump and seals off the manifold..

Basically looks like a distributor shaft with the TOP cut Flush with the mainfold.
