ECU options for supercharged motor

[750hp]

What are the reasonably priced options for an ECU with the capability to run a supercharged motor (ie: 3 bar MAP sensor capability) with low impedance 96 lb/hr injectors?

Emissions compliance isn't an issue, as it's not for the Cobra.

I was thinking that there must be countless supercharged LS series Chev engines making decent numbers with the factory ECU and a tune. Any ideas on their suitability for a 900ish HP application, and what an ECU / harness / tuning function is worth?

Any better options?

Thanks for any opinions.

I'm running one of these and love it to bits.

Too many features to list things like fully programmable traction and launch control etc, etc as well as multiple boost control options. This ecu also has the capability to self tune to whatever AFR's you want to run at multiple map and rpm settings. Will run any injectors or map sensor as it is user definable.

The more you drive the better it gets.

Free tuning software as well as free software upgrades.

Craig,
Can recommend Autronic SM4. Goes to 5 bar.
Can use any injector, autotune, launch and traction control. Boost control etc. Closed loop. Got any specific questions just ask. Looking at Cobber's Adaptronic website it has pretty much the same features.
You can download the software at www.autronic.com.au. (SM4V026)
Cost is about $2,500 includes loom and built in MAP sensor. Can also tune using TPS but that will depend on your application.

Cheers

Also Craig you could contact Blue Power in Melb as they are the agents for Kenne Bell SC's. They were very helpful to me recently when I was looking at superchargers for my 302. The KB is a fantastic product and Blue Power have access to a vast US set of suppliers with experience of all motors.

wrong messege

I should have added that they have a range of ECU options and recommendations... to suit.

750HP Craig The XFI system will work but have heard that any injector over 72 pound is very hard on the injector drivers over long periods on time. This way a couple of years ago. This is way I went with 55 pounds. My 482 motor only uses about 64% duty cycle at 6,200 rpm. You might want to rethink your system and go with 32-35 primarys and go 50-65 secondaries. Forget the map sensor and go alpha n programming using coolant sensor, TPS, O2 sensor, IAT. Map has problems with high lift camshafts and how wide the LSA is. The other thing is get a Snow injection system for water and washer fluid combined. You can have more timing, less gas wash down of the cylinder walls, cooler intake charge, and cheaper to use. It's a high pressure mister.
You need to do some home work with the 1/4 mile guys and find out who running what ECU. My dyno guy said that after my FAST system fails, he want to go to Moldex. Going on 10 years since the last failure which was my fault with a poor ground setup. I learned my leason on that one. If you have the money go doubles. Rick L. Ps look at a TWM setup? I thought that they had a double injector bung hole setup for some motors??

Jeez, I just type a huge reply only for it not to load up when I posted it. Nice!

In a nutshell, I have an M800 Motec for the Cobra engine, and I know that it's excellent and can manage the 96lb/hr injectors without issue.

I'm looking at a similar style of engine that'll need a similar tune. With the countless high HP LS1 / LS2 combinations around the world, I thought I might be able to get a factury LS1 ECU and lightly used sensors for peanuts, spend a few bucks on wiring, then get an HPTuner / LS1Edit upgrade.

If factory ECUs can't cut it, I'd just duplicate my current setup with a second hand M800 and save the dyno time and money by using my current tune.

Thanks,

Craig
