    I may be understanding this incorrectly, but was thinking of a chart/spread sheat/scalar that would show what type of timing curve on could run on varios levels of octain?

    I'm still curious to see if we continue to add advance to the point where we reach and then exceed MBT with no timing corrections. If this is the case, tuning for timing will actually require some intelligence and access to either a dyno, or a good stretch of road and a good dyno calc tool. Too many variables to list timing advance as being appropriate for X octane, but for straight E85 I'd probably start with the timing curves you typically see from piggies running aggressive tunes - 10ish rising to 14ish.

    I'd still love to see a screenie of a timing table for a straight E85 tune, FBO stock turbo no meth, running at around MBT through the load curve. Anyone want to post one up?? Click here to enlarge

    In my experience thats very specific to each car, some cars like timing more than others.

    Exactly .. Every car is different so add timings little every time, log and check till uou find the sweet spot...

    This is all very exiting. I just ordered a Cobb AP and a couple of maps for E85/Vpower mix as well, I also run around a 50/50 mix. I have maxed the JB4 out with my RB's, but it's holding 17 psi beautifully, and timing is constantly in the 10-14 range as well, but it is leaning out a bit. Hence the Cobb Click here to enlarge

    I may end up going for a 100% E85 map, but I'd like to take it one step at a time to see how the car copes. So far I have to say it is loving the E85/Vpower mix, and I hope to do some dynos next month with a few other local BMW guys. I hope I'll be able to join the next GTBoard event in Sweden, it would be nice to compare the RB car to Enrico and Big Toms cars.

    Meth plays a critical role in those pulls to keep the AITs in check.

    Yes, I know meth is really helpfull, but for normal driving I'm only like max 8-10F above ambient temps, and even when I do 3+4+5+6 gear full pulls (and hit the rev limiter in 6th) and log, I hardly ever get above 120F IAT (in 80F weather) and timings stays at 13+ (no drops) and as soon as I let of the gas, it drops really fast down again to ~10F above outside temp. This is at 17 psi, it may of course change when (hopefully) I can bump that to 18.5-19 psi.

    So IIRC I can start out as a decent base tune to run full e85 by say running stg2+sport and all I need to change is fuel scalier bank1 and 2 to 1.4?

    Start with V402 stage 2 +FMIC aggressive and if your running 100% E85 start with the scalar at 1.300. Also add a few degrees of timing above 3k in the higher load columns. Log, add timin if no corrections, an start the process all over again.

    Setting the scalar to 1.3 on full e85 will lean it up a little correct? Or does the dme just correct up to the 34%?

    DME will adjust fueling to meet target AFR, up to a 34% deviation either positive or negative. Fuel scalar has no direct relationship to targeted AFR but rather to reduce excessive fuel trims.

    ok so did what you said. stge2+ but running stock fmic other than that fbo. weird part is on piggys they run stock timing tables but they run 10-14 degrees whereas even running the stock timing table on AP still only getting 6 degrees at most.

    If you don't have aFMIC you should back the boost down. Aren't you FBO?

    Ya I was. Now I'm running the stock one temporarily until my other one is fixed. I figured the e85 might cool it enough. Temps are in the 140s by 4th gear

    I must not be getting something. My friend has dp's dual cones and jb4 g5 stock fmic, stock catback and he is running a 50/50mix e85. Still beats me and I am full e85 and stge2+agr. So on his logs he runs approx. 10 degrees timing to 13 degrees and about 17psi falling to 15psi. So why when I put my car to stock timing table and load to 172 my car is getting 6 degrees timing and 17psi to 12.8 at redline? but he gets no knock at all and I get 3 here and there.

    So is your confusion about why he's faster, or why he can run more timing and not see any knock events?

    kinda both, and why when I run stock timing table on AP why I'm not getting 10-14degrees like jb4? Cuz jb4 runs stock timing table right?

    Stock main timing table is quite low on timing for the actual loads you hit on Stg2+ agg. Look at the table and compare your logs of load actual and rpm to the table, you're likely riding the right most column.

    This.
    By the sound of it you copy and pasted the stock timing map and pasted it into the stage 2+ timing table. That's not going to work. You've got to trace where your actual loads are and make corrections in those columns

    So I would post the log but bimmerboost wont let me. so if I command 175 load at 5k rpms and I'm only getting 162 I need to raise timing in that cell to bring load up? maybe I'm all backwards lol. I came from hptuners on a corvette and this is all backwards. But ya that's what I did was just copy paste stock table

    Forum doesn't support that extension. Zip it then post it or upload a pic of the log.
