Nope, no way pump 93 is gonna work with an OTS map. No e85 around?

And it looks like 73secs in something more than just a miss happened. It saw the accelerator pedal go to almost 0p and gear went to 0. I dont know what to make of that.

Hi. Its Shell V-Power which is rated at 99Ron here which I believe is like 95 for you guys in the states, yeah.

He's given me another map since, still ironing out some stuff, I might have a little boost leak.....

good deal. Yep, Id say check plumbing close. Im not quite targeting as much boost as you, but my delta between target and actual is closer. So Id say something could be tightened up.

Im not sure that is the correct log. Doesnt go over 1100 rpm and 2.6 percent throttle open. You got others?

Datazap.me Website having trouble again

This is probably the one you wanted - http://www.datazap.me/u/walletsr/mhd-2?log=0&data=3-23

edit
Everything I see looks pretty good. Might want to try a log with a shift in there from 3 to 4.That will let you see if you pulling after a shift and how bad.. Higher gears will be more likely to induce timing pulls also.. but I dont think you will have a prob like it sits.

Hey all - for the next couple hours datazap is going to be down as I move everything over to AWS. So in the mean time go drink some beer and do some grilling.

Sorry for the inconvenience but there were some issues popping up on the servers I had been using and needed to do this ASAP. Moving forward there shouldn't be any more downtime!!

Also just FYI i'm working on a Windows and OSX datazap app with some cool new features. So stay tuned!

[Walletsr]

Thank you but the low pressure sensor jumps up and down wot it doesnt hold a steady pressure

??? Not sure I understand your comment. Pretty sure OTS maps are designed to work with a spectrum of fueling. I ran OTS maps with 92 octane for a while before getting an custom tune with no issues.

Yes, but the variations from one motor to the next means that some will have timing pulls on the same octane and maps while others dont. Specific application (x drive or e93 which add 300lbs), climate, humidity and air density also play a role. If I recall correctly, the previous log this individual posted had a lot of timing pulls (over 3degree) on adjacent cyls on some other fuel. Based on what I saw on his latest log, that hadn't changed. ..

Yeah, that in of itself I dont think is an issue on straight 93. ITs more of a prob when you try to push it with ethanol. You got ethanol in the mix? Mine varies from 74 to 54 at WFO and thats on straight 93.

I would think your aftermarket pump should move a little more.. but not sure first hand.

[Walletsr]

The log pictured was with e40 but it is doing the same thing on 93 I have the fuel it stage 2 lpfp. I took it out and checked everything last night and all was good. Only thing I could think of is lpfs is bad

Repeated events below 50 are the sign of probs on a factory pump. I would think that thing should stay at 60+ at least. They flow 2x right?

[Walletsr]

Yeah it's supposed to flow at least 150% greater than stock. I tried looking online but didn't see a log with someone who had similar issues. I know some people said LPFS was bad the only code I get is 2aaf

Ah. Got it. You were being specific to his case, not generalizing. I agree with what you posted above.

This has been sitting on my dev machine for long time now, just too lazy to polish everything off enough for public consumption, so some ideas for you while you're updating

[Smokey33]

Cant find a leak, no idea what It could be.

what is the hardware again? FBO? Aftermarket CP and Dvs? Any of that been touched lately?? I cant recall the specifics..

Okay Sgop335 - I've finally got back to this...I've logged the other parms you mentioned. I also tried lowering my 'base' wgdc from the lower rpms and the car DOES feel better but still seems slow to spool and has an odd 'dip'. I also lowered my overall boost a wee bit.

This one you can see the 'step' in the rampup on the boosts. Not sure why/how to fix?
http://datazap.me/u/bluemonstr/006st...=2&data=3-6-21

This is just the spool from 2.7K to about 3.5K rpms (which you can see is not smooth at all).

i hope i did this right, i used mhd auto log feature from 3rd gear floored it till redline

http://www.datazap.me/u/bxdinster/lo...&data=3-10-21#

this is my first data log every runing mhd stage 2 93oct on a fbo car minus an intake system

3rd gear WOT

Both logs look fine for boost, good job. First log i could say there may be a slight boost leak. Any obvious places, vacuum lines etc you can think? Notice after 5300, pid gets much highr than base? Its telling needs little more base there. Also not sure if you reduced dfactor multiplier..

Im not sure if you have any concerns but something abnormal took place at about 15400 (in the log) about the time it shifted from 3rd to 4th. If you see that in more than one log Id try to find out why.
