406 1.9 TD ECU RESET

Post by Daws »

Hello there, Nice forum - just joined!!
My question is how to reset my ecu on a 1996 'n' reg 406 1.9 td? I have fitted a 'Hydrogen booster' and I want the ecu to relearn the new driving style while being assisted by hydro gas.

Regards, Daws :wink:

Unplug it for a few secs
<steve_earwig> I think this forum is more about keeping our cars going with minimal outlay than giving our cars more reason to go bang

The 1.9 doesn't have much in the way of an ECU anyway since the injector timing is mechanically set at the injector pump. You stamp on the gas and it squirts more diesel in (timed in sync with the cam) only the 2.1 had a programmable ecu.

What's a "hydrogen booster" anyway ??

Oh, if you want, have a sniff around the 306 DTurbo forums as they "tweek" the 1.9 fuel pump manually for more peformance an a trial and error basis :|

Edit: I've just You Toobed "Hydrogen Booster" :shock: good luck fella :?

Just Googled it :shock:

Be fascinated to hear how you get on, please keep us posted.
What difference(s) do you notice already :?:
2002 HDi 2.2 Exec Estate, (2008-12) (wonderful)
2003 HDi 2.2 6-speed Exec Estate (2012-19) (also a gem)
2009 Citroen C5 2.0 HDi VTR+ Estate (godawful heap)
2008 BMW E91 330i touring (great fun - murdered by a reversing SUV)
2007 BMW E91 325i touring (slower smoother quieter)

Hi Guys, Thanks for the advice. Am I correct in believing my car has no lambda, no oxygen sensor infact no real engine management at all? I like things simple!! I will keep you all posted on the hydrogen booster, but I have had loads of problems with it. Been trying to set it up properly for months now. I will get there!
