Hello Guys.

I have a Nissan Almera 2.2 DI (NOT DCI), Year 2000, Bosch ECU: 0 281 010 141 (EDC15M+1-5.3)
Fuel Injection Pump Bosch VP44 (With a Pump ECU on it)

Can somebody tell me, where the Tables for the IDLE Speed are stored ?
In the Bosch Main ECU (0 281 010 141) or does this ECU Just say to the Pump ECU "Lets IDLE" - And this values are stored in the Pump ECU ?

I wanna Raise the IDLE Speed a bit (800 RPM)
Can somebody around here help me with it .

I think in the Bosch Engine ECU is a AM29F400

I Guess this Files are all the "same" Probably somebody have one original and can modify it to 800 rpm IDLE for me, if its stored in the engine ECU

I guess MPPS with EDC15 should read/write it on the Bench

Many greetings from Europe

Hi mate, once I had to do that job. And increase it using a KTS Bosch diagnosis.

Hi, Thanks for the Information.

That means, its stored in the Pump Control Unit, which is only Diagnoseable with Bosch KTS. OK
As long as i wanna get me a KTS 540 (Because i can diagnose every car in FAmily and Friends with it) its a good Decision. I wanna use it With Esi 2013/03 (Not Esi 2...)
Can you remember , where in the KTS Program i can find this option ?

Start the KTS Software- Connect to the Pump Control Module (PSG5) , and then ?
I think , with the KTS, i have to get a Cable where i can connect the Pump Control Unit to it .
Something like that:

Pump Cable (https://www.ebay.de/itm/155310718221?hash=item24293d7d0d:g:YMcAAOSwVdpjmuP p&amdata=enc%3AAQAHAAAAoL5FWyIMk%2FXD%2FK%2B07OULBEi sWvgnSp4jkRHL2zYW3k7SCKPATvFm9uqK9YPYRpj1xv95vjmLs 1j3gjEWtgipbSYmWx%2F%2Be%2BKcJORQGOav68ZSzjQ9%2BAB 7knnsn28dri8oCrnKRhLsBOTQdRHAy2CDSmZh67%2FTUK2t3vv XkAY4xdKCr%2FGZoAXdCo6YdMh5wFbMBveShi%2B1YWV62zTPq tuzNMo%3D%7Ctkp%3ABk9SR_bS-pfAYQ)
(Cheaper Options ofc always appreciated :) )

OR, is it stored in the Engine ECU, which only a KTS can edit ?

Greetings and Thanks ;)
