I tuned a 2011 today that has a lightened flywheel. It threw the p0300 like crazy. It was not misfiring. I think the flywheel is setting off the code.

 

yup. This is my life.

 

I have a light flywheel that will be installed soon. I'm hoping I don't have the same results, but we will see. According to Eric (at SSP), I will have the P0300 issues.

 

I have the streetlite flywheel from ACT, which is lighter than stock (i believe) but not by much. I wanted more mass for drag anyway at the time.

I had a lot of P0300's before, like at least 1 a day, so i assumed it was my flywheel. But now with a new tune/tuner those seem to have gone away, so i am thinking it was actual misfires probably from running lean during cruise/idle.

So I am guessing the reason Tephra or people are hestitant to add a p0300 disable is it could be used for tuners to easily cover up actual problems. But might have to if lightweight flywheels really are that bad, who knows.

 

I had a local tuner flash the v1 into my 2008 MR and do a road tune. Before that, we put the car through it's paces to get the stock numbers with a racelogic for comparison. We used the launch control to get the best possible 1/4 mile time but it would not work anymore after flashing the v1. Would the v1 disable the launch control feature?

Thanks!

If there is one thing I could have changed about my build it would be the lightweight flywheel. I hoenstly wish I would have just stuck with a resurfaced OEM. Its not like these are 350z dual mass flywheels that weigh 42lbs, I thnk they are 12lbs or something stupid light already.

 

I so need to bypass this p0300 had ams tune the car and still have this code popping up

 

I suggest you find out why you are actually getting the code first

Well I asked ams and they told me it was common on the evo x , iam not sure what else to do

 

[QUOTE=tanksmith;10233485]You have a light weight flywheel?

 

[QUOTE=hotstix;10235902]No but I do have a twin disc setup

 

tephra!!!!!!!
ralli 2009 please

 

Is the tephra mod available for the 2012 GSR X's yet?

 

I believe that you have to Email Tephra for those.

 

oh ok, thank you
