CJM Report: Effects of E85 after 3 years?

synolimit

interesting the oring looks fine in the damper yet tar is in the system. somethings getting eaten up. i think ill do e85 as needed and 93 the rest of the time. should hold off any damage indefinitely.

good to know; i didnt want to spend $42 on new ones. just hope the system is easy to bleed. i hate bleeding fuel all over the place.

Phunk - you know I had that black plastic/tar/rubber stuff in my fuel pump housing too. Noticed it when I did my pump. I have also noticed it in a few customer cars at work when doing fuel pump related repairs. Still not sure what it is either, but I'm pretty sure its coming from bad fuel/contaminated fuel. I can't think of anything else that would cause it.

600cc would just barely be enough. I see no reason to not go larger since the pricing on injectors under 1000cc is mostly the same or very close.

You would not need to upgrade/replace anything in the system for E85 compatibility purposes... everything in there will hold up fine.

I cannot imagine any downsides to running a slightly oversized injectors. Generally the only reason people stay away from extra large injectors is for idle quality and tuning concerns. But using high quality modern injectors, we dont need to worry about that with typical sizes like 660, 720, 880 etc etc

Phunk, Did you ever get those plugs pulled to check out your piston heads? I haven't had a chance to pull mine either. But planning on it this weekend.

I havent yet! I havent been giving my Z any love at all... having an affair with a new motorcycle i just bought a couple weeks ago. I am on the verge of getting caught up on everything, and when I do, i plan to get back on the intake manifold project, which would be a perfect opportunity to check on the plugs.

Cannot believe I missed, I really have no fears of e85, just want to do it right so I don't have problems or failures.
Seeing this really makes it seem like on the Z, it can be easily done. Going to shoot you a PM phunk.

thoughts on a stand alone ecu?

Nissan 370Z AEM Infinity EMS Stand Alone ECU

Flex Fuel Compensated: Infinity makes automatic adjustments for ethanol content and applies them to fuel flow, ignition timing and boost target (sensor is not included).

Im pulling the trigger on E85 soon, but id really like the flex fuel option even though i have E85 next door

There are currently no known standalone ems' that are setup to run the VVEL system in the 370z. While some systems are probably powerful enough to do it, anyone that is not at the advanced skill level of engine management system configuration and calibration would not be a good candidate for attempting it. Realistically, the application will need big time direct support from the ems manufacturer. If anyone wants to run a standalone, I would recommend supplying the manufacture a detailed article on the VVEL system and asking if they feel like taking it on.. And I wouldn't believe their answer until they have actually looked at what VVEL is.

what he said I know motec has done it but last i checked it was north of $16k setup for it. vvel is easy enough to lock out, and then you have a wide selection of standalones, but it is definitley a race only option for sure.

Phunk, will you replace the gasket under the lower mani to heads or just reuse?

so lets revive this lol... i'm n/a and plan on going e85. according to a shop here in atlanta, i'm looking to gain 10-20whp from going to e85. they stated that stock gtr injectors would be all that i would need.

I would agree that injectors are probably all you will need for a naturally aspirated E85 370z.

As for power increases, that might depend on how far they are able to push your ignition timing advance. I believe someone around here recently switched to E85 and their tuning software was unable to allow them to advance the timing enough to take advantage of the fuel, providing them no power gains.

i asked them since another member failed to make power with uprev and according to them they said i will 100% see more hp with uprev or with ecutek. so i'm assuming this shop will be able to advance the timing enough.

Having never personally hit a limit to what UpRev will let me do with timing in the software, I would also say that. But now I am not so sure, since I am not yet able to determine why he was not able to reach more timing advance. Right now I believe that shifting around some other table settings might allow it, but I dont know that for certain yet. We will most likely find out soon enough since we just got another 370z for our own all-motor project and already have UpRev software.

ever since ecutek came out with the 2nd version everyone is saying uprev is garbage now, but i don't feel like paying another $600-700 for ecutek. i hope that they're able to do it. they claimed i'll get 20-30whp. i don't see how that can be possible, but they mainly tune gtr's and other high end cars
