Columns C,D,E,F are timing correction on each cylinder

h is Rpm

j is requested boost (never shows more than 2490mbar)
K is the actual boost

m is rpm
N is mass air flow readings

P is timing angle

Car is looking happy and healthy :)

Any questions please ask. Due to very little space for high speeds I could only get a 4th gear run from 3640rpm to 6460pm. To red line the MAF readings get upto around 340 :)

What map? 18 degrees peak timing angle isn't huge, especially with WMI. Looks very happy, but also has a lot more potential. Did you log lambda? Specified, actual and Lambda correction?

Is 2bar + of boost common with the TTE420?

Yeah plenty timing advance potential and the turbo is flat out past 4k mate n75 100% duty cycle. Whatchannellsfor lambda actual vs specified?
 
Is this still the APR 2+ file? 30psi as measured by what? VCDS (The MAP sensor) won't see any more than 2 bar of positive. I wouldn't be surprised if you were hitting more.

Lambda correction is 001, not sure on specified/actual - will be obvious in the measuring blocks though. 20's or 30's from memory.

Can't help but think that with less boost and more timing, you could gain more without pushing the turbo so hard.

Would love to see what Niki could do with your car :)

95 :D . Whats preventing you from running on the 98, I assume you had a reason to dyno with 98?
You are running the APR in line pump, not the LPFP APR drop in tank pump, correct?
 
Any plans with the mapping side of things WeeG? Not tempted to get it to Niki? Would love to see the full potential of your setup
 
I know mine isn't exactly the same spec as G's but it is similar. Once mine is back from R-Tech it'll be interesting to see what the similarities are. :)

I NEED G's Manifold! ;)
 
Did you get any error codes running the 98 map? My timing pull is zero but I keep getting a maf fault code.

Maf error came up in mine and needed mapped out :)

I see, that explains things. Was it mapped out by APR, do not want to change tuner as my logs are looking good with APR.

I guess I could just ignore the fault code, do you know if it affects performance?

It does not effect performance :) just out of range on software due to airflow
 
Logs from my TTE420 set up, BWJ engine, APR S2+, APR LPFP, WMI, 98 RON, 98 map file, catless, 4th gear pull.
Some misfires due to 8 degrees (need to revert to 7's) sparkplugs but overall very strong pull with less initial boost peak at low rpm (according to my buttdyno), linear performance. I think a dyno would output a nice healthy strong graph
Maf readings (355) look promising, duty cycle (62) tells me turbo is not being pushed, more room available...
