Hiccup At WOT

[kwambe5]

Hello fellow VersaTuners!
I have a map that I have developed from a combination of my old 93Oct and some of the stock tables that come with Versatune that I have used to develop a CST4 map for E30 mix. I have recently been having a slight hiccup under WOT, usually at higher gears/speeds. I cannot seem to see in my logs unless I am missing something that you people who have more experience can see.

Mods are as follows; Corksport - HPFP, EBCS, TMIC, 3" Intake (w/corresponding MAF cal), 3" downpipe, CST4 turbo, TMM insert, RMM. Self-made 3" exhaust, EGR delete, dual catch can setup, Damond PMM and short shift plate, SURE Rear differential mounts and weighted shift knob,

We don't have your tune to confirm this but it looks like boost cut 100%.

Here is my tune in its current form.

Ok, so I looked again at the logs and correlated with the tune.
It looks like things start to oscillate when the injector duty cycle exceeds 100%.
With those target AFRs, ignition timing, boost limits and spool strategy you will kill that turbo pretty fast.

[kwambe5]

Ok, are there changes that you would recommend? Reduce load desired and back off the timing?

[mituc]

Considering how the tune looks like I'd change it all. At this point hiring an e-tuner would not be a bad move at all.

Gotcha! Thanks

Post a log. List your mods. State which OTS tune you're using or post the tune (only if it's made by you. do NOT post it if it's made for you by a professional tuner as a paid service or stated otherwise as non-public information).
