First off sorry for all the questions, this is all just very new to me .

I was running the standard ms2 firmware. It was giving me problems so I changed to ms2/extra. I loaded everything properly from the site and loaded the firmware onto the ms. Everything looked to be working fine so I entered all my previous settings and set it all up to what looks right. My problem I think lies with the crank pulse table. The ms2/extra table is in % pulsewidth while the standard software was in milliseconds. The car would start well on 9 milliseconds cranking pulsewidth at 60 degrees which is the average temp around here at the moment. So how would i convert that 9 ms into percentage on the new firmware? From what ive read its a percentage of my upper req_fuel. My req_fuel is at 8.4 so to achieve 9ms id have to run about 110%. But the default value at 60 degress F on ms2/extra is around 250% which is much higher. It said on site to start with the defaults but if what I said before is true it would be much to high and would flood my engine(which it seems to be doing). I dont even get a hint that it wants to start. So am i correct and I should use around 110% as a starting point?

Also something that has been bothering me is my req_fuel. I want to be sure its in the ballpark. I have attached a picture below of my settings, does this look right? As you can see in them im using 4x550cc injectors. The engine is bridgeported, does this mean my req_fuel must be any different from a stock engine? What would I adjust in the calculator to compensate if this was the case?

Also can I use the VE generator with my VE table if im using alpha-n. Atleast for a basic starting point?





Thanks

What version of MS2e? 1.0.2 or 2.0?

oh sorry its 2.0 the one that came with the ms2extra megatune + firmware package on the msextra site.

Do you actually have 4 injectors? Are you using staged injection?

yes i have 4 injectors, im using twin throttle bodies...each with 2 injectors opposite each other so I use simultaneous injection. heres some pics of my setup so you can see what i mean.

so any ideas on my cranking pulse and req_fuel? Can someone post their cranking pulse settings please?

if you are planning on running the injectors staged, you should only put in that there are 2 550's (since alloting for the other ones is done with the staging parameters).


BTW, that is a REALLY NICE intake setup... gets me a little wet
