Put your foot on the floor and rev it out to redline, you will feel the difference, if not you need a better 85 tune.

I put it to the floor several times last night. I can tell a difference, but its faaaar from night and day. Most of my passengers can't tell a difference. It only made 12whp and 5wtq more than my pump gas tune...

Yes, both tunes are on the base map and will requre to be adjusted, especially after installing the header. Just waiting for the 1.13 tunes to come out.

I don't really care much what degradation, if any, is happening... I'm not going back to 93 anymore, startup issues or not. My car likes the corn juice! You probably just need to get your E85 tune tweaked a bit if it's not running better than your 93 tune. |

Update: The 2-crank startup came back again, and it was 80+ degrees-F this morning too.. Started up fine on 1 crank for about a week after switching back from 93 octane though. Still not sure what the deal is, but guess that's a minor price to pay for 104 octane fuel haha

Do you have any way to log your fuel trims? Shoot me a PM if you want me to look over some logs etc... He is in GA, we have been on summer blend for a bit but i think it is still mixed in the station tanks... my local chevron tests at E80 straight from the pump. Back on topic.... have we figured out a way to spot check things yet? Is there anyway to add an inline filter outside of the tank that would potentially catch any debris before it got to either fuel rail?

That is a very good idea. I run an external filter in addition to the cage sock on my other car (turbo). It would no doubt be difficult to do using the hardlines so you would need to run a new braided fuel line to your rail. Wouldn't be too big a deal for the added insurance.

For the guys having e85 start issues it's not likely related to the filter. On the Hydra we use secondary maps for e85 and there is a separate map to deal with the e85 maps during cold start. On the oem ecu you guys probably have only one map for cranking enrichment and you just need to add more.
Also turn the ignition on and wait about 3 seconds before cranking to pressurize the fuel rail again. If you have changed your fuel pump you may not have sealed the pump properly and your fuel system is not holding line pressure. When my car was oem there were times even on pump fuel it wouldn't start first crank so, key on, wait 3, crank. As for the fuel filter failure I really don't see this being related to E85 as it's really no worse as a solvent than pump fuel and I would bet additives in race fuel are worse. Typically the reason e85 is more corrosive is because it absorbs more water and it has a wicking or drying effect on some rubbers. The rubber issue is low concern as the oem rubber lines etc. on Japanese cars have proven up to the task over very long periods of use on the Suby and Mitsu crowd. |
