as they're have been a couple different trucks that have broke the 4200 rpm limit that smarty was holding their customers back to.
When EFILive first started getting serious about developing a product for the Cummins there was a common trend of complaints from Cummins owners & tuners expressed to us.
The one you mentioned above is one of them, people could rev the trucks to 4,200RPM but the fuelling up there was so low it was not worth doing, you got nowhere.
Also that being said when did smarty raise they're limit up to 6k? I hadn't heard this.
They have said it's coming in a future update, but will it fuel up there? We had trucks turning RPM higher than 4,200 when we first released our software in June. We demonstrated high RPM's were not the full answer for maximum power, so we spent our time working on fueling to make those extra RPM's useful.
I should note that when using EFILive, customers are not limited to 6,000 RPM, The ECM's RPM limits don't exist using our software now. Fueling on the other hand; we've run out of test trucks to test limits at full fuel at or above 6,000RPM. I'm sure soon enough someone will want to give it a shot.
And I'm not trying to bash or be bashed. But I feel that smarty has held some of it's customers back with it's 4200rpm limit.
Stating hard facts shouldn't be seen as bashing, it has been a limit in existence since the first 5.9L after market tuner was released. It has been an issue that everyone who wanted to go fast or pull had expressed disappointment and frustration over. EFILive is the first to overcome all the fuelling/RPM issues on the 5.9L ECM, this Starlite Diesel thread clearly shows that.
Smarty has not held anyone back....since day one they have had the most full fueled rpms...till now...where stand alones and efi just caught up...so they bumped it again.
EFILive hasn't been playing catchup at all, our first release was EQUAL to the handhelds in RPM and Fueling.
We've been busy writing software only for GM vehicles for the last 6 years while all the Cummins tuning companies have been telling you all that it's not possible to do 'x' or 'y' with the factory ECM. When we first starting seriously looking at the Cummins ECM in 2010 I said it's a ridiculous claim the ECM is not capable of high RPM's, the hardware processing power within the 5.9L ECM is more than adequate for keeping up with an engine at 6,000RPM, yet alone that mystery 4,200 limit.
Since EFILive was released for the Cummins not that long ago we've proven that the only thing limiting the Cummins has been the R&D (or lack of) by those that have been doing this for as long as you can remember.
They've had years to try to figure it out, they couldn't, but for them the bigger problem is now they are competing against 5, 20, 50 (endless) new Cummins tuners who have the power in their hands to produce tunes equal to or better to what has been available in the handhelds.
I am thouroughly looking forward to releasing tuning for the 6.7L ECM, after we do we might need to get a job on Myth Busters :smirk:
