Lots of timing corrections at high rpm_MHD Stage 1_Log posted

bcoffin23 · 01-22-2017, 09:53 AM

Car Details

82k
Recently walnut blasted
New spark plugs
MHD Stage 1 ACN 91 OCT map

I bought the car a month ago. Currently it is bone stock aside from the MHD Stage 1 map

I have not yet replaced coils, so that will be next on the to-do. Any other recommendations for flatlining those timing corrections through the RPM band?

Could be fuel, plugs or coils.

Looks like you have some shithouse fuel. Do you have access to 93?

Brand new plugs. OEM spec Bosch plugs.

Could be coils for sure, haven't touched those. Likely fuel.....

Lovely state of California makes that impossible.

Currently I am running the Stage 1 ACN 91map. May add 1 gallon of e85 and flash the 93 OCT map.

Thoughts?

You would need to add more than a gallon from what I understand. Plus, you'd need to know the ethanol percentage at the station you'd be using. This is from an ethanol calculator but the #'s are based on the ethanol content being 85% ethanol. From what I understand it can be substantially lower depending on the time of year as well as region. Probably best to test it if you want to know for sure. These are just for reference as I don't know enough about E85 to speak facts.

Thank you for the reference. Ill start with 2gal, do some logs and report back.

Me personally, I add 1.5 gallons every fill up and run mhd stage 2+ 91 map

NO! Add 1 gallon of e85 and leave the 91 map. It's already knocking its ass off.

Adding 1 gal e85 and leaving 91OCT is advice I have heard as well.

How will that reduce timing corrections under heavy load?

more octane = less chance of detonation

That's a simple formula. I'm planning to start with 1gal and do the same logging

bcoffin23 · 01-30-2017, 10:57 AM

Update: I filled up with 2gal e85 and the rest 91oct. Almost all timing corrections are gone.

I would have suggested adding another gallon to try the 93 map, but it looks like your LPFP will get angry if you add more E to the tank.

Thanks for the input.

The only mods I have are a secondary cat delete and afe stage 2 power intake.

I'm going to do lpfp, charge pipe, BOV, intercooler, and catless DPs all at once then flash stage 2
