What are you asking?

Also, this should really be posted in the tuning sub forum (I think).

^ If I move it the O.P. can't post there, Craig.

Carry on.


Yes, that's the choppiest dyno chart I've ever seen. Unfortunately it tells us nothing about your tune.

 

[Calan]

Ahhh... gotcha.

Its tuned 15 psi but feels horrible beyond 15. And feels like the guys at Mac motor sports didn't tune it very well. I have afc2 and flashed ecu all supporting fuel mods would dsm link be even better then this setup or cost to much for little gain ?

Well with ECMLink you can log your ECU to see what the issue is and it's an actual tuning device. The AFC is just fooling numbers to the ECU.

Don't forget he said he's using a flashed ecu as well. Do you have a tactrix 2.0?

OP, if you have a flashable ECU, ditch the AFC.

Ok how about if ecu wasn't flashed and safc was only thing running 880cc injectors would it cause this kinda dyno. The thing is this car is like a soup with to many cooks hands in pot. Things are said to be done to it when I bought it and really aint and finding random parts that are after market that wasn't known of.

yea you wouldn't get smooth timing advance. Also, im sure someone is going to come in and say that the plot smoothing value is 0 but that correction is not for somehting drastic like this.
