Looking to get some feedback as I'm moving along in my turbo build. I have not done my first start yet, but looking for all of your guidance on a base AFR/Spark/VE Table. I know there is tons of research done already out there, and I have done some to come up with what I have now. I modified my existing pre-turbo maps to get this. I do plan on taking this to have it professionally tuned, but want to get it up and running at minimum so I can work out as many of the physical issues as I can before the Dyno. Any advise is appreciated.

*Note:
SpeedyEFI engine management & I am looking to make this build more conservative, even when its Dyno tuned.

AFR Table based on a little research:


Modified Ignition Advance table based on a little research (Do not plan on running more than 7-8 PSI to start).


I have not tweaked the VE table much, I'll do that a bit more once I can run some data logs.

 

AFR and Spark map look good, very smooth and conservative, if you have good fuel.
VE just depends too much on your setup

 

I have 93 readily available and plan on running it consistently.

 

I think your timing in boost is awful. It doesn't transition in a sensible way. Why are you running more timing at 150kpa than at 136kpa? Why make a huge jump from 150-166 and then no change 166-180.

Great questions, hence why I'm here asking for help! Thanks for the recommendation. I'll smooth out those sections.

 

It's not that it keeps you from going or to a tuner, no worries, that timing map is okay to dial in your fuel map and safely drive around, if your base timing is set.

Sure, there is room for improvement, but I assume that you get it tuned by a professional anyway

 

Send me a pm and I'll share my timing maps with you... Currently on my phone so sharing files is a pain

 

 

AFR Looks good, ignition looks a bit agressive in some points and conservative in others

 

Care to elaborate?

 

Transition is a LITTLE hot, but nothing to worry about with good fuel and base timing set, like I said in the other thread. Pull 1-2° in the entire 100kpa+ part of the map and you're good to go

 

could you email me this tune file?
