RomRaider. I am currently running my 1.5X tune if I remember correctly. It doesn't take advantage of all of Shiv's new work, but I would be more than happy to share it for the cranking tables.

Now that I'm back on 93, I just realized this morning that the crickets had gone away while on E85. Of course I realized that because they came back!

gain on stock car in USA was dyno around 15-20 hp with our crap fuel our gain likely to be closer to 20 as we would be down a few hp due our crap petrol. @Wayno had some dyno numbers from aussie cars

The difference for us would be greater than the difference for the americans. The 91 tune will run almost knock free on the street with P100 and requires about 2 deg taken out to stop knock on the track on the exact same tank.

Wayno - You in sunshine state ? I do exactly as you just stated although I don't use united petrol, I use shell 98 for the top up which sh1ts me really :/ It's still too bloody cold here.

try malts cranking table enrichment values link in first post

As far as i know cranking enrichment is for 2nd crank and later. Always starts 2nd crank on pure e85 anyway so no point.

where did you find that info ?

Wayno · 11-11-2014, 03:16 AM

I assumed cranking state number was the number of cranks and which starts at 2 which is why everyone reports great results of being able to always start on 2nd crank when editing those tables but it's probably a calculation the ECU does based on some voodoo and not the number of cranks.

Chuckle... not even close. It's not clear, but in all likelihood it's the various stages of start up that are referenced by arghx7 earlier on in this thread:

Can you post your rom up please mate?

I tried E70 (40L E85, 10L P100), knocks heaps. I could try 77% next (45L E85, 5L P100), but easier at that stage to run straight E85 i think.

That is based on the 1.42 ROM but the cranking tables are the important part and have my revisions.

Just remember:

Looks good

Fuel trims good

AFR looks bit rich probably due residual petrol in tank lowering E%.

slight bit of knock -0.6 again probably due residual petrol.

Will try a tank of united once this one is empty and see how that goes.
