@3100 rpm

VTA1 0.80
VTA2 1.61

inj duty 13.6% on the cells in question

The TPS is within parameters via Chuck's notes

 

Duty cycle is normal, mine does the same thing. Minimum duty cycle is normal to increase as duty cycle is a calculation of how long the injector is open to how long it can stay open. AS RPM's go up the injector has less time to open.

I have the same setup now with 850 primaries and 1600 secondaries. I am thinking of ditching the 850cc primaries for a set of 660cc Greddy Type ND topfeed. What do you guys think of using 660cc primaries and does Greddy make good injectors?

 

I absolutely can not get my car to run anymore. I used to just change he spk plugs and it would run fine. Now it only runs for a few seconds and when I pull the plugs out they are wet and black. I can't tell if it's the premix fuel or a bad oil seal internally.

I have tried so many things. I have tested the spark plug wires, ignition coils, pumped the fuel tank and replaced the gas without premix, downloaded dataligitsoftware and set a -0.4 lag, went off on an oil pressure and sensor tangent, tried adjusting the fuel map. I am broke and exhausted and have nothing to show for it

 

Upload your map. Why don't you just get 550cc's? What are your power goals?

I origionally went with the 850s because they came wihthe kit I bought. I'm now more enlightened so I'm going with a smaller injector to have a more controlable idle. I don't want to drop all the way down to 550s because I took the time and effort to get a new system so I may as well replace it wh something with more potential while I have everythng apart. I think 660s are small enough to have a more tunable low range with respect to min duty cycle. My goals are 550Hp I have a large street port and a T04Z on my gaage floor to install once I get a reasonable base tune with th new fuel system.

The site will not let m upload any pics or files right now.

What do you use for cranking mS between 20-30 deg C?

 

After looking at your map, you should run a compression test ^
