ok ive checked everything over, and i have spark at the coil. also spark at the plugs.. on number 3 plug, around 1 spark per second or there abouts.
plugs are wet which suggests to me the tune isnt right for the injectors and its drowning. ive set the inject flow to 0.0445 and divided the crank stages by 3 and still nothing.

can someone have a look at the tune and tell me what im doing wrong?

Can you post up a photo of your memcal showing the resistor packs?
Chance it maybe a V6 or 4 cyl one, so resisitor pack will be wrong causing overfuelling.
Can be fixed, just need to make sure. If it has a knockboard on top of the resistor pack a photo of that or the the code printed on top of it would be good.

thanks for the reply.

im using a DSFesty nvram and Festy RT board with a 7.5k resistor in the R1 position

7.5K should be right.
I'm not familiar with Festy's boards, but hopefully he can confirm everything looks OK.

the only thing other than wiring and ecu that was changed was these deka injectors. i might take them out and fit stock ones and stock tune to try get it to start. dunno what else to do

I presume your able to connect in TP so the NVRAM and ECU are working ok? So in TP there are two flag items that you can use to check the memcal a little. One says what the code is set for (the 4/6/8 Cyl Mode) and the other (4/6/8 Memcal) to tell you what memcal is installed. The memcal flag gets read on a ref pulse with the default being 8cyl, so crank it over (make sure you can see the RPM trace show something like 100RPM) and see what those flags say after that. Will be able to confirm the memcal config is set correctly.

thats weird when i connect and crank the dash goes nuts with wrong information. ive tried echo on or off and its not picking up hardware but it connects

heres a log.. something isnt right.

shows 8 cyl mode but doesnt show memcal.

showing 28,000 rpm on cranking with 80% duty cycle on injectors..
any ideas why?

Something is still very wrong there The logging is ok as other sensor readings look stable, but RPM spikes are def bad! To confirm there is nothing corrupt in the running code, is the bin you posted earlier a read using the flashtool? If it is then its not corrupt.

With the memcal flags not showing anything, and if its not getting all confused with the sus reference signal and high RPM, it normally indicates TBI mode - which would be firing the injectors on every ref pulse instead of every 4th. Explains the flodding! Will need to wait for festy to let you know what to change for that. It does not effect RPM though, just fueling.
