Having throttle closure on stock map, any ideas? TC was turned off

Z4 35iS with v8.0 1+ using an Wagner EVO1 intercooler running 99 RON fuel.

It looks to me as though I have a boost leak / solenoid issue as in the mid range boost doesn't track target but this is all new to me so thoughts appreciated.

I started at to low an RPM and didn't fully disable TC due to concerns over weather conditions.

In the next run I started at the correct RPM however I'm sure TC would have kicked in due it being a bit damp which I think is evident is throttle closures.

stock maps are horridness - timing retards all over. They dont really prioritize anything like a aftermarket map does.

its more likely you are hitting the limits of the S1 map- Yes boost is slightly low but it really only shows up at about 5400 rpm and up. Move your mouse along this horizontially and you can see when the load request begins to approach load target you start to get throttle closure. Then zoom out and do the same thing

There was a 1/10 tank of gas left from the original e30 mix. Not sure how that would contribute to the corrections

But really this will tell you more - https://datazap.me/u/volfwaley/stage...-22&zoom=31-65

You got a 3 degree retard in the middle of the third gear pull. Its prob gonna happen on more than just once cyl after the shift into 4th. Some reasons for this is you are showing a lambda AFR of mid 12s and short term trims are pulling fuel. That combined with your ambient air of 14.1psi means you are prob at like 1100 foot elevation in tx.. somewhere lubbock I Guess.

So, an Off the shelf map especially on with an ethanol mix will cause some fuel mixture issues at higher rpms. Your options are custom tune, or back down a bit...

I think I know where this is going next..

Oh, and you only had it floored for about 4 secs in 3rd. Best thing to do is roll into it in second at about 3K and run second to 6250-650, leave it floored thru 3rd, and get a little of 4th gear.. Yes, its prob not going to be legal, but thats gonna give you the best load for 8 to 10 secs.
;-)

I live in San Antonio Texas so kinda close yeah 😌. Lol ill see if I can get some highway logs in then because that kinda speed is almost jail time in the off roads

So if 9/10 of the tank is just 93 octane, then an E30 map is way too agressive with timing so you get timing corrections...

can someone review and let me know how I'm looking?

I’m running a 93 octane map I guess I put down the E30 fueling by mistake on the log. I was getting timing corrections on the E30 map as well. Anything I ca do to change that other than getting a milder tune?

Did you sample test ethanol content and mix accordingly to get e30 mixture correct? Too much knock across most cylinders.

No need to log all of the "timing cyl. 1-6*crk" timing cyl. 1*crk only is fine to see timing.

Edit: Log Load actual and stft 1 and 2

Yes, tested ethanol content, verified its true e85, I had about an 1/8 of a tank of 100 octane in it and put 5 gallons of E and the rest 91. Ive had nothing but issues with MHD, thinking of going back to JB4.

Thing ran strong and no misfire up top which was surprising.

yep. good baseline
Along with Throttle percent and load req.

The log you posted above is for sure an E30 map, maybe you did it by accident? I can see that because at the bottom right of your log parameters it tells you which map is uploaded etc... I've checked your account and indeed the last log you made (but not posted) is stage 1+ 93 octane, but that's not the one you've posted here.

Always flash the map that best matches your exact mods or you will get timing corrections, high IAT's and fueling problems etc... And yes you need to lower your map with the lower octane rating. If you car is stock the max you can run is stage 1, choose the octane in function of you fuel quality so that you don't get that much timing corrections anymore.

Hello,

Two logs, second one might be better.

Please take a look, stock 2007 E93 107k miles running 91 pump gas. Per, previous owner it has a Dianan stage 2 tune. I just finished a walnut blast, OFH gasket, and new front belts and pulled. I have a receipt saying plugs and coils were done 20k ago.

I think I have a waste gate rattle, when I lift off the throttle it kind of sounds like a old clock winding up with a key, or would that be the common exhaust issue?

Any diagnosis will be appreciated.

Thank you

I have heard of the Dinan oscillations but see it now in your logs. Throttle oscillations like that are very undesirable. This is caused due to boost mean oscillating to meet boost target caused in turn by the wgdc pid. The oscillations are visible in all of them. It would suck to pay for a dinan tune to get this (understtod car came w it) We have come a long way...thanks to mhd
But it s a good baseline...timing seems high may be the tune was for a higher octane

Better log from the other day, I still need to capture one with the recommended parameters selected. To me this looks better, it was a decent little 3rd to 4th pull and left a new 5.0 standing still....

Seems to me you're still not running enough Ethanol for that E30 map, a lot of corrections and your lpfp isn't that low...

[Paliator]

Can someone help me with this? I purchased my n54 with mhd stage 1 plus on 93 v7.0 (haven't had a chance to buy it myself and the last person didn't include the tuner) but I have a vent gauge and consistently my max boost psi is 15.2 and target is 15.3. Shouldn't the boost be higher on stage one plus?

I had 1/4 tank of 100 octane, then added 5 gallons of E85 (verified) and filled the rest of the car with California 91. I dont get it, I have fresh plugs (1 step colder NGK's) and fresh eldor coils as well as a fresh fuel system with index 12's. Ill take another log and see where Im at tonight but maybe I should drop the tune to ACN 91 so I dont hurt the motor. Really missing my Jb4 at this point.

I think the MHD tunes follow the vin so you should be able to just connect the car with the app and review.

Not necessarily, the target will depend on iat, and other ambient factors, 15.2 psi for a stage 1+ seems ok.

I believe that MHD app will follow VIN + Google account.

Thank you for your reply. My friend on a newer stage one (not plus) is hitting the same boost as me. I believe he is v8. So that is what concerned me.
