BM3 OTS MultiMap Full E85 Dyno + Questions

[satinf82_]

Has anyone dyno'd the BM3 Multimap with full E85? How much hp should we have when running full E85?

I also heard that the injector failing issue is not as common when running full E using the OTS map. Is that true?

I'm also having a nasty misfire on cold starts when running E50 or above. Any solutions?

I can't say that I have seen someone post a graph with the multimap on full E but i'd be curious to know as well!

As far as injector failure, I think the majority of members would advise to run E60 and under to avoid potential failure but a may be wrong on that.

I had the same issues on my car when I switched to the multimap on E60. Spoke with hellokitty who suggested to switch the HPFP setting to "original" and I also removed the cold start. With that the issue went away. I am not 100% sure why the cure to this is the cold start delete but it is what worked for me.

I dont really want to use cold start delete, any other way around it? I already have my HPFP set to original.

Only way to resolve it is to either switch to MHD or ECUTek (like I did).

I have a 3 slot custom flex tune. Not sure how cold it is where you are, but you shouldn't have any cold start issues if its 60F or so. Not sure i have ever ran Ethanol below 60F...

I have dynoed mine with with different levels of E. Keep in mind my tunes are all road course based.

I've had an injector get stuck open on a E50 custom tune before the revisions were even finished (45k miles)

Did you have a filter on it for the E? Like Bend Calibrations fuel filter kit.
