Default **AWESOME timing and IAT graphs with and without W/M injection; 3rd & 4th gear pulls

After Advancing the timing by 4.5 degrees... I made two 2nd to 5th gear runs; one wihout W/M injection turned on, and one with it turned on. Here're the results

After the W/M was turned on....


As you can see... the timing corrections on code 20 have dropped considerably.

It would show better if you just did one gear pull (3rd perferable) from ~3k to atleast 6500rpms. This way people can see the timing curve and pull. Also if you graph iat's, it would help show the temp drop.

Looks good however Chris, should be able to go one more increase. I guess you have the correct nozzles in now or was it pump being to low (150psi instead or 180psi)?

It was actually both; the nozzles are correct now and the pump is up.
I wanted to show IATs too... but I forgot theblock for the manifold temps. I do have the bost also on the raw results, but they would have cluttered the graphs. Im actually bored right now... and its 2:30am, maybe I'll look up the code and go make two runs in 3rd gear. The reason I made a 2nd to 5th gear run... was because if I made a 3rd gear run it may end up being kind of short. and difficult to convey in graph format. then again... on that graph, 3rd didnt start below 3k, it started at around 3.8k.

any other blocks you want me to capture on this run?

Actually....

I keep a Book full of all my results and logs from all these runs, along with Vag-Com instructions and functions.

Anyone know where I can get a full list of the Fault blocks for the TT? That would be an AWESOME resource to put in the front of my book for reference

Just the stuff you have in one gear if you can get it would be great. The higher rpms the iat's climb and so does the timing. As for the turning, go with the 6* pull rule and you should be able to max out your current setup.

Default RE: Some Graphs

Whats the 6* pull rule?

Is that just setting the Timing to 6* advanced?

I can do that and graph out the temps, timing, RPM, and timing pull
With and without W/M

Alrighty, I'm gonna head out and log these real quick.

Be back shortly.

YOu can increase timing till you see the cyl1-4 cf up to 6*. Right now with meth you are up to about 4*

Well i just got back.
I turned the timing up to 6* advanced and made 4 runs; 3rd gear from 2.5k to 6.5k with and without Methanol, and 4th gear from 2.5k to 6.5k with and without Methanol.

I logged blocks 04, 10, and 20; RPM, IAT, Cyl 1-4, and Timing.

Im processing the data logs right now. Graphs will be up shortly

Grrrr... looking at the data... dont think the W/M kicked on.
pulled the injection hose and tested it... nothing. gotta check some wires real quick. If I get juice.. Ill run again.

-sigh-
Ok... it wasnt that the injection wouldnt turn on... it wont turn OFF, so the test results were comprimised.
Im gonna need to just go ahead and install a toggle switch instead of wiring it to the foglights. Right now the only way to turn it off is by turning off the headlights completely (which makes the 2nd-5th gear runs okay cuz it was during daylight with headlights off and then headlights and foglights on)

Im gonna just make two runs with the power wire pulled... and then two more with it back in.

be back shortly
