Steinbauer P Box ‚?? Failed on the road! @ ExplorOz
2004 Prado 120 TD auto
53000 k's and never had a problem.
I researched the various diesel chips and as I phoned around to find a reasonable price for a Dtronic I was recommended the P Box and I was convinced. So I ordered one and had it fitted.
I was surprised initially at how cheap the P Box build quality appeared. Plus, the way it was mounted on top of the relay box in the engine compartment looked dodgy. It was held in place with cable ties meaning that to get into the relay box I would need to cut the ties and this meant I needed spare cable ties.
The connector to the box is unsealed against dust and moisture and being in the engine bay it would get it's fair share of both of these ‚€“ plus heat.
The wire spliced to the accelerator wiring loom looked susceptible to damage and I did not like the idea of the original wire being damaged.
So, we pay our $1500 and we are off to drive home. It feels great. Plenty of extra torque and more power ‚€“ OK!
It worked for one month testing it around home and on it's first real trip pulling a 600 kilo bush trailer the unit fails and the engine dies on the highway 800 k's from home.
OK, so you can unplug it and replug the original connectors restoring the engine management to stock but what if we had been overtaking a roadtrain and the damned P Box had failed? What if my pregnant wife was 100 k's from home and the thing had failed?
Steinbauer (Diesel Care) supplied a replacement P Box. The replacement was SECOND HAND! And, it failed just as the first one had, except it failed within 10 minutes rather than a month.
Thank god for the 30 day money back guarantee.
Take my advice and buy a Dtronic. I just installed mine and I reckon it provides a smoother power band and it looks like it was engineered and built to go to the moon. Being mounted behind the glove box it avoids the dust/moisture/heat problems of the P Box placement ‚€“ and the connectors look like military spec.
