Setup settings for Holden V8 #52

Post by NickZ » Sat Sep 28, 2019 8:08 am

Hi
have a few questions regarding the setup for a Holden 304 V8 engine
I have a 36-1 tooth trigger wheel
8 LS1 coils in paired configuration so wasted spark
8 injectors paired wired like the firing order.
my firing order is
1-2-7-8-4-5-6-3

1. I can't find a firing order in the firmware (tunerstudio) that I can use.
2. I can't find away in the settings to select the 4 paired injectors to fire as pared like the wasted spark.

I am using my own custom board and have had it bench tested as a 4 cylinder and works great. I made one mistake and used PD14 as a coil out and have found it is default firmware fixed as a fatal error led, how can i change that easily. (im not really a coding person and could move the pin in the next revision of my board, but would like to test the current board on this engine).

Welcome to the forum!

Just added your firing order into the firmware.

To move PD14 you would need to recompile firmware. If that's not trivial for you, I believe cutting a trace and hacking hardware with a jumper wire could be the best way forward :(

four pairs of injectors sounds like "batched injection mode" to me?

to get a understanding, my current ecu fires injection and coils in sequence, channel 1-2-3-4 and repeats in its batch paired injection, does this firmware fire channel numbers in firing order as selected ie: channel 1-2-7-8 my firing order 1-2-7-8-4-5-6-3.

Yes, firmware accounts for firing order while decided which cylinders are batches together in what sequence

you should see this in engine sniffer tab of rusEfi console

ok. i have had the engine start but only for a few seconds, using the engine sniffer i get coils and injectors with a good trigger pattern then injectors stop triggering but coils keep going, i can keep winding over the motor and coils keep triggering in the sniffer and the TDC line is at correct time.
i have a screenshot just catching the last injection pulse.

After more testing anything over 500 RPM cuts the injectors and they wont come back until rest.
here is the current tune.

Please post pictures or videos of your setup for our entertainment.

Please post a log file to help us help you. With your symptoms this sounds like engine works in cranking mode but does not run when it switches to running mode. MAP sensor not working/connected?

this are my Basic boards i have for Speeduino, i make a Arduino 2560 board to plug in, now im trying the same with RusEFI using the stm32f407, there is also a version of speeduino for STM32f407 but is not user friendly and i can't get it to compile at this stage.
I make a few other boards too that this plug in MCU will work on.

did you mean stm32f407 both times?

"everythingfuelinjectOIn" is that a typo in domain name in PCB?!

All '1'. But really just turn off "Use fixed baro corr from MAP" for now.

I wish I had your enthusiasm, because this must be your 20th ECU.

this base is a production model ive been working on, With plugable brains is now universal.

Had the car running today. Runs awesome with this stm32f407 and RusEFI.

next is full sequential.

Congrats!

Hopefully this would eventually be the first rusEfi v8 which actually moved under rusEfi power - so far it looks like all v8 engines were only running while parked :(
