Es9j4s custom ecu

[Mohammad208 0]

Hello

I have an es9j4s v6 engine in my 405.

The engine comes without oem loom and ecu, for this reason i must oprate engine with after market ecu

And i need some info from engine.

Firing order ?

Which cylinder is no 1?

And fly wheel tooth number and how many degree to tdc

And next question is about vvt or cvvt, my ecu has not support cvvt, and i dont know the engine is vvt or cvvt?

And last question i want to run engine with waste spark System, and i must pair which cylinders to each other?

Sorry for bad English and thanks for reply

For standalone you can for sure think of DP-Engineering: https://www.dp-engineering.nl/vems-pnp-psa-3-0-24v-es9j4-xfz.html

For the rest, I do not have the answers, but searching on "Es9j4s standalone management" I do find several topics/forums where they are talking about using this engine in different cars and/or modding it.

firing order is 163 524, cylinder 1 is flywheel end front, cylinder 4 is flywheel end rear.

 

most aftermarket ecu companies have FBW capable ecu add on modules or direct ecu control.

 

flywheel is the typical 60-2 pattern, no idea what the angle is though,   running wasted spark you may be able to use the older ES9 coil and leads,

 

 

there are dual cam sensors and dual knock sensors, only one cam timing solenoid.

 

 

best bet to be honest with this engine unless it is being tuned is to run the standard ecu.

Thanks for reply

So the cam timing is vvt not cvvt

That mean i can control the timing with my ecu,

I dont know what you mean by cvvt

[SRDT 146]

Continuous Variable Valve Timing... what PSA was calling VVT at the time. Simple on/off VVT was then called VTC by PSA.

They later started using the CVVT name on EC5, EC8 and EW12A engines.

 

On the ES9 engine it goes as follows:

ES9J4 -> none

ES9J4S -> on/off

ES9A -> continuous

Thanks for reply,

So the job is easy,

Only building loom and setup the ecu.
