Livernois Tune Issues?

Have you 13+ owners had the fuel module recall done?

I had mine replaced and yes they have to remove the rear seat to get at it etc. But my car was having shifting issues before and after the recall. Again, it doesn't happen all the time, just sometimes mostly when turning a corning and then going into WOT or if I hit the gas, back off a second and then go WOT again it will completely miss 2nd gear and red line as if it went into Neutral! Hate that, luckily it's not every time. But if I go from a dead stop it never misses gear.

I would return to stock see how it shifts. You can reset the tps sensor. Disconnect the battery and make sure terminals are not touching the post and get a jumper wire and connect negative to positive that will clear any memory. Start it and wait till it get to normal operating temps then turn it off. Restart car wait a minute then jam a/c lights and accessories for another minute then drive it around I noticed a 60 mph road and easing to about 75 then cruise for few more miles then try wot. See what it does turn it off restart and should be pretty normal
But go threw some gears. If the idle is not learned correctly car acts up. I have done many tunes and revisions via data logging. I have felt the 2nd gear lag it acts that way in leaning but after some miles everything gets much better. Try that see what happens.

OhaHahn, mine has done just like your. I leaning towards the nannies kicking in when we punch it, come from a turn. Since it never showed its ugly head while I raced last year, think its just a quirk.

So I am not one to look a gift horse in the mouth but my first to second (fall on your face problem) just went away a few days ago, I have done 50+ pulls 0-60 and not one hiccup. I was curious if you all think I should still be worried about it, or just take the blessing and move on?

I dont know if it makes a difference but the only thing I have done differently is get my fuel at a place that has "a bottle of Lucas fuel treatment" in every premium fill up. Doesn't sound like something that would matter but thought I would pass it on nonetheless.

A certain Grey Ghost owner adds MMO to every fillup, or at least used to ...

 

[BamSHO]

Still think he does.

Once per month on the MMO...

Thing with turning and going WOT....the sensors are thinking roll over. After tuned, the amount of torque we are producing combined with wheel angle resembles roll over conditions.

Makes sense... LMS recommends mixing race gas with then 4+x to make sure there is no KR...

The MMO + E (or E alone) is a decent substitute.

On the 4+X tune the fuel pressure holds above 2000psi on regular gas, so there is more than enough room for an E20 mix..

I use the MMO as a lubricant for the fuel system since I run a mix of e85...nothing for performance, just a precaution against the corrosive effects of e85 on the system that isn't designed for the possibility of water infected E85.
