E85 now wont start

I'm assuming it wasn't supposed to start shaking and varying rpms? The hz also went up past 120 im guessing from the surging?

**hellssephiroth** · 08-30-2013, 04:41 PM

should I have changed plug gap or anything prior to the e85? I have bkr7e i think they were in it gapped at .40

Yes during the rpm surging you'll see spikes in the airflow.

I fail to see how spark plugs have anything to do with airflow.

sorry if i am being an idiot about this.... I just realized i have no idea what im doing and its frustrating me....

im just wondering about the shaking. Or is that just because of the fuel being added and pulled

**Greg E** · 08-30-2013, 08:21 PM

Fuel being added and pulled. See what going on is your MAFT is telling the ECU there is a LOT of air so it adds the fuel. This brings the RPMs up which draws in more air and more fuel. ECU realizes the RPMs are too high so it cuts back fuel. Cycle repeats.

What you have to tell the code is that 80-100hz isn't a lot of air so it doesn't keep adding that fuel and driving up your RPMs.

BTW did you ever turn that bit back on and reflash???

**hellssephiroth** · 08-30-2013, 09:07 PM

heres the log.

**hellssephiroth** · 08-31-2013, 07:27 AM

That was before I messed with the table

**hellssephiroth** · 08-31-2013, 07:46 AM

sometimes the 02's spike up to like 80-0 is it supposed to be the small spikes or the big spikes? I think I know how to make them big or small thats why I am wondering.
