Listening​ to you fight the tune strategy makes me glad I'm only messing with an eec-v CDAN4 strategy. I have it easy with the turbo.

This thing is a bear for sure. Just when you think you have it licked it shows you who is boss. Going over my last log, my final tune must have made some more power cause I exceeded every tq table I could find to raise and I still got TB closure on shifts. This car is going to fight me all the way to the 10's.

And conversation and knowledge sharing was what the interwebs were all about I thought. I have nothing to hide. I don't feed my kids with car stuff so information is free from me.

Oh the days of simple torque management

Truth Brother.

To get control of open loop in most instances I simply change the open loop mph to whatever I like. It's 50 mph right now. I set stabilized open loop temp to 120. Total control. Modify the transfer function and high injector slope. My startup closed loop short term trims are 1.0 lambda. No trimming to be done.

Maybe you are going about it wrong.

The BMW 335 guys use piggyback to get their tuning.

Maybe you need to replace the pcm with an early non drive by wire and tune it from there. If it was me, I would find a way to drive those high pressure injectors and Lose the stock pcm.

I realize injector timing etc is an issue. With all of the advantages of DI, I don't think DI is the sole reason for theLT1's performance.
Maybe strip away tables with out of range parameters to limit their usage.

U need access.

Maybe the Ford idea of dual injection can be utilized...ie, port inject a A/F ratio of say 22:1 and DI the rest. Gasoline won't fire at that ratio but might get you the fuel outside of the pcm's abi!It to monitor

I am for sure not a tuner, but I only look at Lambda because it will be stoich at 1 for 93, and 1 at stoich for E85. I stay around .83-.85 lambda at WOT.

The stock ECM will do what is needed. It just needs to be cracked and figured. Doing a one off deal with replacement or secondary ECM's would be cool but not for the masses.

There is a guy that has developed an IM that has conventional injectors. He has a pretty simple way of running them as far as I am tracking. I think he is shooting for 1,500+rw with his new build. Goertz is his name. Pretty cool looking manifold.

Using Lamda for fueling like you are doing Poppa makes it easy. 1 is 1.

I was going to say wouldn't tuning by lambda be easiest because the lambda value is agnostic to fuel type, right?

Yes, it is. I am slowly making the conversion. Depending on the software thought you have to understand EQ as well.

I see GM going the same route FOrd did with the upcoming Coyote... Dual injection setup. I think the new 5.0 is going to be a hit with the DI and not having the drawbacks(carbon buildup etc) with the added port injectors. Much easier to upgrade fueling too.

I doubt it. That's a whole lot of money to change the LT1 just to make it easier for hot rodders.
