EFILive Beta First Impressions

I think we kinda hijacked the thread.... we should move this part of the discussion to a new thread and discuss slipping trans and dyno #s there.

This thread has been on track for 45 pages. I think that's already a compd record. LOL
 
scan tool looks bad a$$. keep uo the good work!! BTW has anyone made the switcheroo from an SCI to CAN ecm yet. hard considerations here.
 
2011 will the best Easter I have ever had thanks to Team EFI Live. Thanks Cindy for update

I dont know if this has been asked yet or not so please forgive me if it has......and dont bash me for heaven sakes!

How is EFI going to compare to smartys new SSR tune?

Anybody find the RPM limit tables with the Scan Tool yet??

I've got a puller with a test pull this weekend and the season opener on the 23rd...love to have a fully fueled 4500rpm+ truck for the opener!!!!:rockwoot::rockwoot:

At 4500, the stock ECM will be an eye opener. :)
 
I believe he is talking caps in the ecu.. there is a way to squeek more outta the ecu though. they have 4100 fully fueled. I Think a truck fueled to 4100 will be cats ass compared to what we had last year and the fact that we can log it.

Ah ok....I hope EFI can crack the RPM limit...but at least help us fully fuel up to that limit!!!

Last year 3500rpm fueled was ok, but pullin would be better with more rpm.
 
Been sayiong it for about 2+ years now, the stock ecm wont do alot of rpm it just doesnt have the capability in the hardware even if you could get around the software. Maby I am dead wrong but I dont think I am. If you want to get full fuel to 4500 then you need a stand alone. With a stand alone I have had full fuel to 7000rpms...

I know lots of people are saying it isint possible, but I'd like a definitive answer from EFI, before we go standalone.

There is a shop in town working on a conversion of an 04 to an 06 ECM for a sled pulling truck so that we can tune it. Sounds 'simple' in that all the old stuff comes off (injector harnesses under the valve cover, etc.) and the new stuff goes on. Also sounds expensive - but I guess we will see in about a week.

If it goes well, i'll be sure to post about and if we have any issues when it comes time to tune it.

What I can say about the 5.9L ECM is the CPU inside it is more than capable of keeping up with high RPM's. For the technical people, the CPU is the same one GM use in their gasser ECM's from about 2006 up, these will run a gasser up to about 8,000RPM with way more complex computations than the Cummins ECM needs to do. The scaling in the ECM's RPM calculations allows up to 8192 RPM!
So the CPU speed is not the problem, it has been suggested the Injector driver circuits are the issue, that may very well be the case because the charge capacitors need 'x' time to recharge to be able to fire the injectors. Switching them too fast may indeed cause overheating of the internals of the ECM.
However, soon we will be able to log the pilot, main and post injection pulse times, if it shows even just the the pilot & main are being used up to 3500+ RPM then above this turning off the pilot (and post) increases the available time the injector firing capacitors have to recharge.
Even though the pulse time is much shorter on the pilot, if the injector only needs to fire one main shot it's going to give the ECM more time to recharge the capacitors.

Cheers,
Ross

Hardware doesn't seem to be the problem.
 
But with efi how many beta testers have huge injectors? Thats the key for the injector caps if that is the only known problem???
 
I think most of the beta testers had mild trucks until all the bugs were worked out.

Thats what I was thinking, wait untill they get a truck with 300+ size sticks and see what those injectors caps are doing.. takes alot less to push a 300hp injector than a stock injector trying to make max power...
