Interesting info guys, thanks.

I did more toying with the settings this morning and got to thinking. If the ASE is a percentage of Req Fuel, then lowering the Req Fuel should result in higher ASE numbers. Mine were extremely lower, fo some reason through the tunign process i got the idea i was way ...

Lately I upgraded my firmware and corrected my Req Fuel. Req was high due to some bad info i received and believed. Was 7.1 and per MT is now 6.4.

Here are my symptoms:

Cold Cranking 40~80 the engine will fire initially, continue on to fire a few more times and die. Adjusting the ASE is difficult ...

At this point i am retuning with a newer code version, once i get everything stable and tuned i will post how things are.

I might have a couple leads. Could be code related since i am on a code that does not appear available anymore. Could also be my AFR blowing out spark. After some discussion the ...

Eric do you think an uncalibrated TPS could cause similer issues?

At WOT the MS ECU only thinks the TPS is at 77% when its at 100%. Perhaps the MS ecu is seeing a slight movement or slight variation in the TPS voltage (.2) and it is altering the VE as it preps for decel. MAybe i am out on a limb ...

The forum wont allow to upload the log where the ve dropped out. I can send it via email if anyoen wants to view it. I tried to make it smaller but then log viewer cant read it.

Here is my msq.

thats the most logical thought and thats what i started to think but why would i have this problem in the winter. Could it be more dense of an air charge?

Here is another thought. this condition doesnt do it all the time yet my intake temperature is always around 70 when it happens. its also around ...

I will get the datalog file up tonight so everyone can see the issue. Right now i am at work and the file is on my laptop.

I tried Loading a newer file and ran into a lot of communication issues. Post is in the Megatune section.

Thats whats strange Eric, i dont have any RPM spikes or falling out. My Map and RPM are only increasing so my Fuel should increase. If you look at my datalog on a long pull you can see how the MS reaches 112 but stops climbing.

In the instance with where i am breaking up while accelerating from a ...

Is there a max Amount MS 1 will tune in a VE?

Here is my problem: At 4500 RPM X 198kPa, i am feeling some type of mis. Looking through datalogs i cant see an RPM drop or spike. The Datalog shows the correct RPM point and Map point but claims the VE is only 112 when the bin is set to 119. Yes i have ...
