New e30 log. Don’t hit me!

Stock block. Stock exhaust, af intake, recirc valve, wga, some other stuff.

It’s iffy in places. But whaaa! More powah than I should have.

Edit: yeah that’s 550 Plus crank torques!

Sorry to burst your bubble but you are monitoring wrong torque number. You have ttl torque, mountune and everybody else monitors ltt torque. For example, my car stock 354, B3 457, ttl torque today on 93 octane in florida......570.

Sorry

Can you explain the difference? @Thor2j

 

[NitroBlueFTW]

Nah no sorries needed.

I noticed this a few days back and figured I’d leave this till someone noticed.

Good catch!

No worries though. My llt number still kick butt.

 

[moorman]

Yup. It’s sounds to be pretty accurate. It’s the same calculation that the factory ecu uses for its torque targets.

Most of the time I think it's pretty accurate too, but yours is pretty out there; 530ft/lbs at redline doesn't seem plausible for the mods.

Assuming your pulls are on a flat road and your RS weighs similar to mine, vDyno has your pull at 401wtq & 333whp, which is more in line with expectations.

My power-adder mods are similar, minus the WGA:
Accessport
ECS FMIC
AEM air filter
E30 tune

Edit: just saw what Thor2j caught and that makes sense. I'll leave my links because....data

 

[NitroBlueFTW]

Can you explain the difference? @Thor2j

One removes estimated drivetrain and accessory loss. One doesn’t.

I dyslexiad them. My fault. But I still blame who ever named them ttl and ltt.

I’ll do some rips with appropriate log setting and post ASAP(next week as im biz traveling again).

 

[Thor2j]

Can you explain the difference? @Thor2j

TTL Torque Final – The final engine indicated torque as calculated by using the "TTL Torque Base", divided by the gross torque ratio modifier. On certain applications this can be logged with the "TR Ratio TTL" monitor. This value will be fed into the Torque To Load table lookup and return "TTL Load Desired".

*LTT Torque Final – Engine brake torque measured by incoming airflow, includes all compensations for torque loss from accessories, friction, etc

Nice. Who ever what’s smart enough to calculte that crap might have been smart enough to name them somthing significantly different.

Ah well. I lose.

Walks away.

Have fun y’all.

I have the b3 kit and IC will be here next week making it a B7. I dont care what the numbers say it makes the car what it should of been from the beginning. Love it.

Alright you guys. Here is the final revision. Only took two. Corrections are on point car is smooth.

i have a question on these data logs... why does the AFR always creep up above 13 between 3000-3500 rpm, then slowly drops down from there? i recently installed a 93 octane tune from Stratified on my car and took some logs. i noticed the lean AFR in the lower RPM on every log and this concerned me a little, but every RS datalog that i have looked at does the same thing.

 

[NitroBlueFTW]

I’ve been noodling the afr thing too. It’s even exaggerated a bit on e30.

I wonder if it’s our fuel system lagging a little behind a wildly fast spool. Our 3rd gear logs happen in seconds. That boost curve goes to peek in half a second or so.

No idea what kind of FPS our ecu runs at. I’d hope 120hz.

You realize the lower the number the richer it is ??

 

[NitroBlueFTW]

I’m sure he does.

I see it in my logs too. Afr is wonky while building boost and for a 1000 rpm after peek boost happens. It trims Fast to stoich just after peek boost pretty well. But the struggle is real for the first few k of a 3rd gear log.

I think it’s part of, or a limit of 3rd gear logging. We are going from a 2k rpm bog to wot redline.

 

[SVT_4_me]

yes, of course. the logs show the AFR going lean (higher number) around 3000 rpm up to around 3500 rpm.

my 4th gear logs look identical with respect to the AFR curve. i am still waiting for my revision from Stratified and i posed this question to them. we'll see what they have to say.

 

[NitroBlueFTW]

Are you logging 4th gear like 3rd? Essentially bogging to 2k rpm and then flooring it? Or ripping from 3rd to 4th at wot and then logging 4th.

I imagine there is a big difference in how the puter deals with a rippin 3rd to 4th shift, vs a coast to 2k to a wot rip.

 

[Thor2j]

Is there anyway to overlay 2 logs to see the graphs????

 

[NitroBlueFTW]

We all dream about a datazap that can overlay multiple logs. Maybe if we all throw cash at our screens.

 

[NitroBlueFTW]

new log. e30, 3rd revision. logged with ltt torque this time =D Does anyone know how to calculate stoich or the correct afr for e30?

Fairly easy to do yourself in excel?
X-axis is time and Y any variable you want to look at or multiple variable, scatter chart, highlight and select data columns?
Once you set up the first one it should be real easy....you may have to reset the time scale to overlay correctly....

I am working on templates for the csv data itself to color scale and set up the trending to overlay charts....snails pace.....

 

[jjameson]

Something like this?....
