Lance's suggest is probably closer, but one thought that popped into my head is a poorly flowing injector (partially clogged perhaps) that is causing one cylinder to be on the verge of lean misfire at idle/light load, under heavy load the PW will be much larger and thus the chances of misfire might ...

Thanks for the replies guys. I will definitely run a flow test on the pump and see what happens. At the moment all the fuel line is new including the fuel tank its self.

I will run multiple tests tomorrow and keep you guys updated on the findings. Also, Here in the link to the fuel filter I ...

I installed a new billet fuel filter setup during the whole ms install. That was only 6-8 months ago. Is it possible for a fuel pump to work on average but then not flow enough when is needed. At the moment im still using the stock CIS fuel pump which was good on a 80+ psi system.

Im using a 3 ...

Thank you guys very much for the replies. As of now the fuel table does look a bit weird. On that map (current) I haven't reached 5500 so I haven't tuned that far yet. Im just trying to make it not lean out up high like it has been. Even with this map the a/f ratio still goes up to about 16 which ...

I asked about the USB-serial adapter last week, and think I have got that problem solved. Thanks for your help. My old laptop died, and along with it my Megatune software. When I bought a new laptop with XP, I had to solve the USB adapter problem and down load a new copy of Megatune. I downloaded ...

I have begun the tuning process. I have run several datalogs and I am confused about what I am seeing.

My understanding is that the low kPa values indicate low vacuum and higher kPa values indicate more or higher vacuum. The fuel Map layout seems to indicate just the reverse. Also so does my data ...

Hey guys, I've been trying to tune up high so I can start making full throttle runs. I've been having kind of a difficult time in doing this. I have realized that I have to add A LOT of fuel up high to make the car run better. For the longest time it would lean out real bad up high. Well its still ...

I would really like to know more about the code but unfortunally I dont even know what C stands for or what assambler does.
I have been looking at the firmware but don't see what is needde to alter
anything at all.

Maybe there is some info on the subject needed for stupid guys like miself.

I know ...

It is verry good to have the 2 VR inputs but I think that in my case
the second one won't do me anny good.
You see there are 2 triggerwheels in my distributor one with 24 teeth and
one with 4 teeth.
I asume that the stock ecu uses the 24 wheel for the rpm and the 4 wheel
for position.
Now I already ...
