Stock block? Sorry if that's been answered a million times.

Shiv@Openflash 01-28-2016 10:59 PM

Yes, stock block. 100% stock fuel system. Even running the original spark plugs (20k miles).

I am assuming tuned with the OFT?

This is amazing. Thank you Shiv@Openflash!!!

Why was the 340whp pull not taken to redline?

NyC Zn6 01-29-2016 08:59 AM

When can we expect to get e85 tune for SBD kit?

ST-A 01-29-2016 09:46 AM

Nice results shiv, kind off the same results i'm expecting with the kraftwerks +OFT, but we needed upgraded injectors :iono:

i'm interested to see the cam timing maps, as that is what we are still testing to keep more pressure in the block instead of straight out of the exhaust .

How hard are you leaning on the DI system here to achieve this? Virtually every other tuner I've talked to says above 300whp or so on E85, you really need upgraded port injectors to keep your DI injection time in the correct window for optimum function.

You are quite above that here.

MisterSheep 01-29-2016 10:56 AM

Nice job shiv! :thumbsup: in for any updates you may have! Makes me want to pick up a SBD kit

The fuel limitation that others have suggested doesn't appear to be hardware based. There are some adjustments I made to injection timing/phase and PI/DI split that got me around this "fake" limit. In terms of logs, I have both PI/DI injector under 80% DC and fuel pressure stable at the target level. There is, quite literally, nothing suggesting that i'm even close to the limits of the fuel system. PI IDC can be dropped further by tweaking the PI/DI split but it looks like the engine likes plenty of PI at high boost.

Every now and then, the ECU triggers what appears to be a 7200rpm rev limit. That's what Rev Limit B is set to from the factory. I raised this to 7500rpm but it still throttle limits at 7200rpm. Working with ztan on figuring out the underlying logic. Initially I thought it was a cut caused by lean-run but there is no evidence of lean run:

Interesting. I saw a thread with ztan mentioning he was doing some investigation for you. Looking forward to your results. I'll be doing some work on an oft350 setup here locally this weekend. I'm trying to convince the owner to go e85, and this is a nice step in the right direction.
