can someone check this out please. Im barely getting my setup running. i have my stock MAF hitachi with ev14 550cc injectors. 38mm wastegate, stock fuel pump, t70 turbo with T4 .68AR hotside. 17psi right now. This log is with a stage 2 file running off of wastgate spring. i have a wideband gauge and its hitting 11.8afr-12.0afr. The pull starts at mark 2333 and ends at mark 2567 in the file below.

Your log is bad, and your approach is wrong. Use ME7Logger, select the typical mark p variables, and get a real log. Why log some random stage2 file?

Your right about why log a stage 2 file but I don't have anything else to start with. The car feels good with this file and the air fuel is ok so far. I know there is way more to it than thay. I will get the right logs. What would you recommend for me to start my Single turbo file? 

I finally had time to log the car. please let me know if i did it right. I used the mark p type logs with visual logger. Also, i have egts disabled, all emission deleted and rear o2s deleted, i dont have my MAP sensor plugged in yet, and using wastegate pressure. I have stock MAF with Hitachi sensor and coded in ev15 550 117 injectors and stock fuel pump on 4bar. My AFR on my wideband is in the 10s on WOT and feel sluggish up top when it hits 10 flat. i open the file below with notepad.

Please post raw csvs.

Ok I'll do that today when I get home from work. Thanks

Mine ran unbelievably horribly without the MAP plugged in.

Misfires, bucking, no boost.  Horrible. Ew.  Get hardware fixed before you do anything else man.

hope these are the right logs.

Im going to get it plugged in this weekend. i fixed some of the problems with it. replaced some coils. put in new plugs, injector seal and boost leaks. so far now the car feels like it pulls good just when my wideband goes to 10flat it feels sluggish. mainly 10 flat on 3rd and 4th gear pulls on WOT.

Logging with hardware that is broken (or that you are about to change) is a huge waste of time...

So ya, don't bother until the hardware is 100%.

I understand. I'll hook everything up and re-log. But as far as logging is it the right way and file format?

I finally was able to get log after hooking up my the Map Sensor and replacing the ECT sensor.

You are not logging enough to do good work. Also, why haven't you increased boost request? I think a single turbo can handle more than 12psi at redline....

Please log wgdc and i-max

Also, why are you requesting so much boost so soon? You're asking for limp... i'd delay peak req load till at least 3k, if not 3.5k

my n75 is electronically plugged in but not being used. Im doing 17psi wastegate spring.

i will go back in and log those as well but im not using the N75. just wastegate spring. where on tuner pro do i go to delay peak request load?

im using this stage 2 file as a base file to work with. Thank you guys for helping and im ready to do whatever so my car can run right.

Not really needed then, but IMO you really should be using N75 control

Thank you for the link. i will read into delaying peak req. i opened it on tuner pro LDRXN_1_A
and not sure what the number mean and how to delay it.

Also, what would be the benefit of using the N75?

Uh. By now you should know the relationship between load and boost :/


:(

Same thing. You really shouldn't be tuning w/o some of this basic knowledge :(
