880s, maft translator, and e85 = workable
 

this isnt for my car but a locals that were thinking about switching to e85. is it possible to tune 880s on e85 with only a maft translator? its been said that 650s is pretty much the limit usually on a translator on pump gas. But wouldnt e85s need for 30% more fuel bump the 880s down to being controlable as long as you ran e85? In theory this should make them 590s. So in theory even 950s on e85 could be controlled with the trans lator becuase they would be equal to 630s. Thoughts?

and no just go buy link comments

Maf't is almost as bad as the apexi Neo. I ran a maft with a gm 3" mas years ago. The car ran ok, made some good power, I think 500some on a FWD dynoguess. This was using 880's and running c-16.

Then I put my AEM EMS in the car and with 10min of tuning the car drove a lot better then with the maft. So I guess you could do it, but there are better options out there.

I am also interested in this.

im gonna guess its gonna be a PITA but idk much about tuning cars, if i were you i would just have your friend see if he has a eprom and just get a chip burned saves head aches and what not

Re: 880s, maft translator, and e85 = workable
 

im not asking what works better then a maft, or how to get super dialed in outside of a translator, this isnt my first rodeo. Just asking if a translator on e85 would handle 880s or 950s

Re: 880s, maft translator, and e85 = workable
 

it did in my talon for a few months before i sold the shell off. stock chip,880s and e85. it ran ok but not totaly perfect. i would get a chip burned for it to start with. i did it just to see if it would do it and like it.

Re: 880s, maft translator, and e85 = workable
 

I got you covered.

Of course you can run it on e85. Back in the day I ran 950s with just a translator, datalogger, scm61, 272s, pump gas. The problem is not the maft. It is timing maps you get when with taking out airflow to compensate for bigger injectors. With the way the system works you will fall under a more aggressive timing curve since the ecu is seeing less airflow. The only counter you have to this (without dsmlink, or a chip burner) is to lower the base timing (1g). There will be a side effect to this, but it is minimal. The car will be a bit sluggish until boost hits, but you will however have the high wot timing advance under control. At around 17+psi with the 950s (I ran 25+psi) I was hitting 25-29 degree of timing advance at wot (as seen with my datalogger). I wanted to peak around 17-19 degrees so I set my base timing to 5 after tdc. The factory spec is of course 5 degrees before tdc. With 10 degrees of base retard, I was able to hit 15-19 degrees during wot instead of the 25-29 degrees the ecu was giving me (the datalogger will still show 25-29 degree of advance, but you will be at 15-19 degrees and all your knock problems will most likely dissapear.

My car at the time went 12.0 @ 120mph with no knock probs. Drove it for the entire summer until I got dsmlink. You probably will not have to retard base timing that much since your injector size won't be as high as what mine were (ecu will see more airflow, closer to stock, giving you a less agressive timing curve). I'd start at 0-2 degrees base and go from there.

The 880's on E85 would be about like 600's. With E85 you should be able to lean out the WOT quite a bit extra.

Re: 880s, maft translator, and e85 = workable
 

the setup were thinking is

2g
translator
880s or 950s
255pump
small 16g
fmic
tuned with Lm1 wideband

Then why are you asking if this is not your first rodeo? I said I ran a dsm with a maft with 880s, making 500fwhp. It works, but its a ghetto round about way of doing it. A Eprom ecu is so much better for what you are trying to do.

I ran 950cc's with a SAFC on e85 and it worked pretty decent actually, luckily e85 likes more timing than gas so its not so bad. retard your stock timing 3 degrees and let er rip.

Re: 880s, maft translator, and e85 = workable
 

They said they are doing this in a 2g, unless there is a 6 bolt swap you could not do this, 2g base timing is not adjustable with the cam/crank sensors.

sometimes we just want to have fun and do things a little different

could be worse i could of made a thread about a afc 1 knob or 5 knob and a Blaha maf

Re: 880s, maft translator, and e85 = workable
 

then try it

Re: 880s, maft translator, and e85 = workable
 

I have run 880s on E85 with an SAFC on a 16G/stock SMIC car. It worked decent enough, we couldn't go crazy with the boost like usual on E85, because it would knock bad above 20psi with the horrible stock SMIC on there and no timing control. The MAFT is a shitty tuning device though, I would take a 2G MAS and SAFC over a MAFT. Like John said 880s on E85 are like running 600s on pump/race gas. The E85 can handle more timing, so it should work even better than 600s on pump gas and if you are able to raise your boost/airflow up enough the timing will drop with it.

lol. do it! I'm considering going e85 sometime next year...hopefully.
