I posted about a month ago with a log review and no boost i have since fixed the boost issue and replace spark plugs and coils. I pulled a new log and would like to know if anything looks off. Also is there any way to know what tune is on the car currently? It does not have JB4 installed.

Holy shit those timing corrections are not very good. It's on all cylinders!

[Mwilliams2123]

What would cause that? What should i look for?

[bimmerguy1210]

It would appear that you have an aftermarket tune. My Cobb on stage 1 sport consistently peaks about 14psi of boost, nearly identical to your log. Stock is about 8psi. However, I add some e85 to the CA 91 to prevent these cylinder timing corrections. Although, seeing timing corrections in every cylinder of your log may indicate a more aggressive map.

I am still running a stock intercooler. I have DP's, CP, DCI, and a tune that i dont know what it is. I plan on getting a intercooler next. Is that the issue

You could be on a map that requires a FMIC or on a map that requires 93 octane. Do you have access to e85?

[Mwilliams2123]

I live in CA so 93 octane is not an option but yes i have access to e85. As far as i know my LPFP is stock

[Mwilliams2123]

If i flash a stage 1 MHD tune into the car will it erase the tune that is there or will it cause an issue?

Yes me too, I am in CA so I have no choice either. Add a few gallons of E85 to your tank (and fill rest with 91, or put in about an E20 mix) and you can log and see if this will help with your cylinder timing corrections. Put the E85 before you put in the 91 so you get a better mix in the tank. Drive it around for about 10-15 min at least then take log. Your stock LPFP appears to be healthy from your log so adding the E85 should be no issue.

And NO, do not flash an MHD tune, or any tune, with another tune installed.

[Mwilliams2123]

Is there any way to figure out what tune it is? How do i go about removing the tune so i can add a tune?

I'm not sure if you can tell which tune is currently installed just by the logs, someone else will have to chime in. But if you want to have a different tune installed you'd have to have the ECU reflashed back to stock, then re-tune.

[Mwilliams2123]

Could i use MHD to flash back to stock or would i have to take it to a dealer and have them flash it?

MHD may be able to provide you a file that can reflash your car back to stock. I would contact them and let them know your situation.

[Mwilliams2123]

Ok thanks will do. Also thank you for your help and info. I will also give the e20 a try

No problem, hopefully you can sort this out. The e20 should help your car run much better.

[Mwilliams2123]

The odd thing is when i bought the car it was stock CP and intake and had no boost due to a vacuum leak but did not throw a low boost code. Also had no timing corrections.

First log : https://datazap.me/u/mwilliams2123/l...-6-7-8-9-10-20

[bimmerguy1210]

My guess would be you had no timing corrections because there was no boost going into your cylinders.

[Mwilliams2123]

That was my thought as well. Im still stumped as to why it never threw a 30FF code

Yes, that is odd. I would do some research on that, there's a lot of information on these forums.

Added some E85 this morning to make it an E20 mix and ran a new log here it is.

I did throw a fuel pump plausibility code with the e20.

Looks like you've fixed those timing corrections! You should have also felt a noticeable increase in power. E85 does wonders for our cars

I wouldn't worry much about that code, especially if the code is by itself. If another code pops up with it then that should be a cause for concern.

That is the only new code, i have a code for both cats and for exhaust flap
