Hi Guys,

I've been running BM3 multimap stage 2 all along. My country doesn't have pump E85 so I have my own industrial ethanol drum and mix myself. My usual mix is E40 ish. Yesterday I finally tried stg 2+ and yes there is a huge bump in torque, 590Nm to 677Nm on the wheels and 400 to 440whp.

Problem is my boost deviation on stg2+ start to increase after 5000rpm. I didn't get this on stg2. Do I have a boost leak? Or is my stock turbo nearing it's end of life. Below are my logs. Any insights would be greatly appreciated.

Stage 2 E40. 93 map. ie map3

Stage 2+ E40. 91ACN map. ie map 1.

Mods
Catless DP
TU pump
Do88 charge pipe and Mera intake manifold
Do88 charge cooler radiator
BM3 tank mounted flex fuel kit
XHP stg3

Thanks in advance.

The stage 2+ map is targeting more boost at higher rpm and your turbo is just not able to keep up with the demand. The turbo isnt dying its just maxed out at 96 percent WGDC. You can see between the two maps that the load target is 160 in stage 2 and 180 in stage 2+.

Hi guys,

I tried MHD's E40 map and experienced massive timing corrections - more than -10.5 degrees on several cylinders and -3 timing delta for knock. I reckon I actually had E45 in the tank, and was running Esso Supreme 99Ron. I decided it was too risky.

I've been working with a custom tuner who has developed this E40 map for me. It would be great to hear what you think, and how much power I can expect to achieve - based on previous E40 logs shared in this thread.

Thanks

The Saga continues. I thought I was finally clearing up. Only using Mobil 93 octane at top tier rated stations. Running 91 map with 93 octane. Still having pretty wild timing pulls.

Where it was starting to clear up -

Thanks bro for the feedback. So do you think the stg2+ map is safe to run? Especially with the timing corrections?
