Wasted days.
Looks like the truck is finally working as it should. It has taken two techs and about 4 days to get this thing running properly Wednesday, we leave on Monday. Up until lunchtime on Wednesday I was about to order a new Alternator for my 1997 Defender to be able to go in that!
This Steinbauer Module has given so much grief since it went in, even the experts can't tell you what is going on, I'm sick of hearing "It shouldn't do that"
Enough of the rant.
We have tried two ECU's and two Steinbauer modules in all combinations. What threw a spanner in was a Fuso software update that was done with one of the chips wired in, it made no difference over standard with the chip on and gradually dialed up on the potentiometer (adjuster inside the module).
Be wary of Fuso ECU upgrades.
The end result of a very long and stressfull 3 days this week, 2 days last week, and countless days prior to that to get this 4 year old truck with 60,000kms running properly with a Steinbauer module is this.
The ECU software upgrade will be installed at your next service if it hasn't already. Make sure that the Steiny is not active when this happens, earth out the grey wire if your Steiny has this option to have it switched off. It may freak the system out and you might not get any benefits from your Steiny afterwards. You really DON'T want to start hearing " It shouldn't do that".
The surging that my truck was experiencing was in a nut shell too much boost/fuel momentarily, the thing would boost up to 27psi and then drop back to 20-23 while accellerating, (making the dropping a cylinder feeling that I was getting from it when this happened). In my truck the factory setting for the chip was set too high (at 12 O'Clock). After all the Bull$#1t we have been through with this over the last few weeks, the short version of the fix for our truck was to bring the Steiny setting a quarter turn back (anti clockwise) to 9 O'Clock. The boost maxes out at 24 psi, so far (in 150 kms) no surging experienced, the benefits of the Steiny are noticable but not dramatic which I am happy with. Time will tell, but we are more positive now.

As a Footnote I bought a cheap Bluetooth OBDII diagnostic thing to plug into the port under the dash for under $20 Aussie and an ap for my android phone for about 5 bucks. It works a treat, can tell you an enormous amount of useful and maybe not so useful information about what is going on with the truck. Brilliant well worth the money, I also got a code reading ap which will give you some idea of where to look if it throws up a fault code, I think that it allows fault codes to be reset as well. Awesome.
