So don't fully understand cold cranking E85 issues. But I'm assuming that that you could turn key to ignition and press and hold an aftermarket installed button/switch. That would warm by several degrees a small component of fuel line as close to the injectors as possible. That in conjunction with suitable E85 injectors and some table variation of tuning tables this problem could be solved. It appears a fuel of the future and R and D will be required for it to become norm. As an aside how do Expensive Daewoo who have E85 comparable cars get around this issue?

I have looked at Factory Expensive Daewoo Flex Fuel tunes but couldn't find the relevant table at this stage to see what they do but something that I wouldn't mind looking at further when I have the time.I have been playing with this fuel running it very lean. E85 reacts quite alot different to Petrol when running very lean fuel ratios in the normal driving areas of the tune.Whereas normal petrol looses alot of power and misfires when running past 17:1 air fuel ratio, E85 does not seem to and continues to make drivable power way past this ratio (I still use petrol ratio for simplicity) and does not seem to miss.It seems that that E85 can be tuned way past stoich on the lean side to deliver much better fuel economy and still maintain drivability.I have seen up to 24:1 (petrol air fuel ratio) on E85 with no misfire and still some power there which is quite eye opening for me.We are takling low load/rpm areas of the tuning maps Edited 17/05/14 05:12 AM by turbotrana 1 Link to comment Share on other sites More sharing options...

However stops any water in the fuel from freezing at high altitude.Also the fuel in the tank is heated by the hydraulics as its used as the cooling medium for hydraulics, very little effect though.

Jet was still in nappies when I first started EFI tuning. Edited 17/05/14 01:50 PM by turbotrana 1 Link to comment Share on other sites More sharing options...
