Yeah the dips at the shifts I wasn't concerned about, it was the beginning of the pull. For about 2 seconds it was about 350 psi under target. I guess that's not that big of a deal though.

Thanks for all the help guys.

I have a couple of logs I’d like someone to take a look at. This E30 from the pump not mixed by me. Trying to see how well it does with Stage 1 E30 flash.

Hey everyone my IATs seem really high after replacing my heat exchanger with a CSF heat exchanger here are my logs. Is there anything that stands out to anyone?

I always forget the exact temp differential but the DME targets I believe 20F over ambient. so if it's ~97 outside, you'll typically see IATs as high as 117 while cruising. It's really not uncommon or something to be concerned about. Especially if you're parked or moving slowly in traffic. IATs drop quickly once you get up to speed, and the car doesn't begin pulling power until IATs are 140+ during a pull.

Thanks kern but it was 70 outside while I was recording this log.

Hi guys,

I would like you guys to help me review my Logs:

X3 M40i 2018 (only mod is the catted downpipe) - BM3 OTS Stage 2 93 octane

I've been using 95 AKI fuel (102 RON), but I've been getting a lot of timing corrections and some knocks.

Here are my logs (4th gear - DSC Off):

not really bad, some minor corrections, but overall timing is ok

FastSleeper · 05-31-2021, 07:41 AM

Hoping to get some feedback on my recent logs. Currently running bm3 stage 2+ 93. Not sure if this tune is a tad bit too aggressive. Mods include AA HFDP and TU Pump. Timing advance is decent and hpfp is holding strong but seems be pulling timing quite a bit in the early rpm range. This also includes 1.5 gallons of e85 to a full tank of shell v power 93. Thanks.

I have an M240xi with downpipe dorch stg2 hpfp xhp. Here is my log on 93. I see timing is being pulled through 5th gear in cylinder 1 and 2?

My 60-130 time is 12.4x consistently.

first cylinder is a bit off

Any idea what i could do to fix that cylinder? Do you think more e85 would help? I have normal stage 2 93 logs and timing is near perfect. Its only impacted on the 2+ map.

i know stage 2 + needs more octane, try some more E85 or 2-3 liters ethanol 100% and log again

Can anyone take a look at these... I've been messing with E30 and 93oct to see how the car responds.

it does well by the looks of it. do you log the target hpfp pressure? i can see the actual pressure, but you should turn that on if available to compare the target vs actual to ensure you are not outpacing your hpfp.

I will check it out... thank you for looking at this. This was on E30 pump gas not mixed by me.

I was worried it wouldnt work... I want to try it with E85 mixed with 93 Oct to see if there is a difference.

The problem with the pump gas is that I do not know what the E was mixed with: 87, 91, or 93

In theory it would only be 15% of the volume of the E 85. So a wash.

Im talking about the E30 mix from the station. I do not know what octane that was mixed with to get the E30 mix, 87, 91, 93?

Ciaran2903 · 06-03-2021, 04:29 PM

Just got MHD and went with an E30 mix. Stage 1 for now (DP on order for Stage 2). Looking with help on the timing corrections:

https://datazap.me/u/ciaran2903/e30-...33-34-35-36-37

https://datazap.me/u/ciaran2903/e30-...17-32-33-34-35

Let me know your thoughts. Is the timing most likely an octane issue? Might need more E?

Log looks ok, some corrections at cylinder 6 at high rpm, you could try some more octane , but overall it,s not bad

sultan340 · 06-04-2021, 08:02 PM

so back with some runs on stage 2+ OTS map this time, with Dorch stage 1 HPFP installed (fuel rail issue seems fixed now).

3rd gear pull:
https://www.bootmod3.net/log?id=60ba...729b321cd73764

4th gear pull:
https://www.bootmod3.net/log?id=60ba...90c607d8fdf7c8

5th gear pull:
https://www.bootmod3.net/log?id=60ba...90c60748a0afb1

3rd -> 4th -> 5th pull:
https://www.bootmod3.net/log?id=60ba...729b321cd7376b

i had cleaner logs in stage 2, (much less corrections). Any ideas what can cause above?
Already did new plugs, coils etc.
