Also put a wire from the distributor to the block to the grounding panel. Everything Zeros out on resistance. What i found was the distributor Has way to much clear on it and will not ground itself to the block. Today im going to look over the MSQ, make sure everything looks ok then try it.
also be sure your grounding matches this guide

It pretty much does. Its a tad bit different but goes in the same order.

as long as none of your sensors are grounded to the car or block you should be fine

coil connected. With the coil disconnected it pretty much stays flat.

If the car starts it wants to run for a few seconds then go all the way lean. Then it goes back to 11.5 afr stays steady for a second then all the way lean. What i dont understand is why i have to set the ms for the injectors to like 5 for it to even hit. there low impedance.

It looks like RPM is lost. There are only a few pulses in that log.

[quote="black 89turbo] What i dont understand is why i have to set the ms for the injectors to like 5 for it to even hit. there low impedance and why does it start up perfect, run for a bit, go all th way lean and shut off.[/quote]

Can anyone shine some light on either situation?

Another thing to note:
Dead time voltage % - "factory" settings.
Dwell Batt Adjustment- "factory settings"

Im waiting on the camera batt. To charge and then im going to get another CSV and make a video. Will be posting soon

I posted all the information. I actually got it to run. surprising. I adjusted the VE table. I still cant run the car with the injector MS say at 0.6. All these were done at 7.0. i dont want to burn the injectors up. I OHM them out and there still good.

The settings in tune 1 seem pretty reasonable

What don't you like about it?

injectors are 450cc Low impedance. There less than 3 ohm. the MS value should be around 0.6 correct?

"Typical mainboard settings

High impedance injectors - dead time = 0.8-1.0 ms
Low impedance injectors with resistors - dead time = 0.8-0.9 ms
Low impedance injectors with external peak/hold - dead time = 0.6-0.8 ms "

The car will only run if set to = 5.0-9.0

Let me give it a try this time, Peter... What "5.0 to 9.0" are you talking about, the req_fuel? That is certainly not the dead time, which you have at .752 (and is right in the .6 to .8 range you refer to).

Im Talking about "bank 1 dead time@ 13.v(ms)". Were are you seeing .752??

Yep that's where I was going, but too tired after bad night at dyno.

Thanks billr...

fix your ve table load cells you are pretty much 35-95 kpa linear then go to 35 then 0 above 95 kpa THIS IS BAD. is there any reason why your afr table is set to 11 at idle? put that back to around 13.5-14.5 and adjust your ve table instead.
LEAVE DEAD TIME AT OR AROUND .750 if you are haveng problems getting fuel out of your injectors raise your pwm current limiting % to 40 then 45 no more than 60.

Ill change the last too to 100kpa? or change all the cells?

Ill look at the AFR table and change it.

I will change the dead time back to .750 and try changing the current. i thought i tryed this already but may be mistaken. Thanks for your time and input.
