Hello my fellow tuning enthusiasts.

I've been running E85 for a while now and luckily I haven't blown up my motor.

I got a good timing map and have been just staying under 3500 rpm's and running a 14.8 in 2k -> 3k up to 30 load.
20mpg on E85!

So now on the problems.
#1. I never get past 220 load. Is this because I'm running out of fuel?
Actually I finally got past 220 load to 240 tonight after playing with latency,
My 14v is now 0.84, up from 0.76.
Up the latency more?
I'm running a scale of 522 right now and I'm going to try 514cc tomorrow.

Any input, advice on scale + latency + 750cc injectors?
anybody else running 750cc injectors with E85?
Mind sharing your latency + scale numbers so I can I compare?

I'm not looking for big power. I just want 340hp and I should be able to reach it with these injectors.

Thanks much.

 

There are some examples to reference in this thread. Just remember e-85 requires about 30% more fuel so multiply these scaling numbers by .7
Something else to consider is a 750cc injector when multiplied by .7 becomes a 525cc injector, which is smaller than stock. One could argue that you will need more injector, even for the goals you've laid out. If not I believe you'll be right there at the edge. What are your current IDCs?

 

at 220 load, 6k rpms I hit 96.1% ..

This morning I got up and lowered my timing from 2.5k to 5k rpms by 3 degrees,

raised my 14v to 0.88 ..

I looked at last night logs and hit 244, this morning I hit 249 ..

No knock though ..

Any more advice? tips?

 

I've searched and never found anyone with 750cc injectors running E85 who posted their scale + latency information.

Sorry meant to copy and paste this link. Most have them scaled at 650 for pump, so 650*.7= 455. Give that a try.

Edit: just saw your IDCs. What are your afr's looking like durring a pull? In the past I've heard of and seen folks going as far as 110% IDCs, but it always seemed fool hardy. As soon as the opporotunity presents itself you might consider picking up some 1000cc. Just my 2 cents.

 

12.0 at WOT,

Yeah, I'm going to switch to 1200cc's in the future so I can run big boost but for now I just want to make sure I'm getting the most out of what I've got .. looks like I'm there.

I guess I should be happy I can putt around town lean as can be and get 20mpg or else punch it and be knock free to 7.5k rpms ..

It's just weird not seeing past 240 load .
