I have the ME-R Maffless and for 2 years I have been trying to get this thing to work better than the Red 106 I had.
are these that hard to tune?
Going back to a Red Armstrong where I was in the mid 10's...:mad:

As long as you have a wideband to go by, it should be pretty simple. Just bump the thumbwheel up or down to get your A/F between 11.0-11.5 and you should be good to go.
What issues are you having?

Even using my Wide Band I see that the AF is up in the 13.0 at Launch. The Car is a Dog for the first 1/8, then it flys.
Car would always run in the 11s and never go under 130 MPH.
I am using Alcohol Injection. So I am leaning it up and still don't know what the numbers should be, and car just cannot make those 1.40s like I once did...

I would shoot for an A/F of 11.0 for now. How long is the A/F hanging at 13.0? Maybe it's not coming out of spool up mode. It uses RPM to determine when spool ends. Do you know what RPM the 1-2 shift is happening?

You're good there. Once you're out of spool mode, the fuel is controlled by the thumbwheel position and it holds that fuel for the rest of the run.
You say is starts around 13.0 A/F. What happens after that? Is it getting richer later in the run?
Is your MER a wideband version, or a regular MER?

Can't tell you what happens after. I use an Innovate Wide Band and the Playback was not working right. But if somweone could give a head start on what my numbers should be at with Alcohol;
like #2 0-1900 Mao Gain
#4 0-4000 Fuel
#B 4000-5000 Spool Fuel.
I sense that during the Staging I am over fueling the Motor and that is what kills my 60' times to be so bad!!
The problem is in the 1/8 after that the wheels break loose.
I have a Chip from you that I never used yet. I can try that and see what happens. (Stock MAF Chip)?????

Shot in the dark...

Exhaust leak before turbo? I had the same issue till I found out my crossover pipe was leaking at the joint. Ran like a dog out of the gate but pulled hard mid to up top. Not running the alky BTW and just Me-r w/o WB correction.

Fast

After taking the engine out, I found many problems.
3 Cracks on the Pass Header, a crack with one of the Intake Ports. But by the time I had the Engine out. I had sold the ME-R and got a FAST. So I would not blame the ME-R for anything. It did it's job.
Oh and a Bent Connecting Rod #4
