There's a fair bit of a verbal stoush going on between some diesel module suppliers right across several forums and social media.
It all seemed to start with the whole DP Vs Red Back performance modules fight but has spread.

Now I neutral in this, I don't have an issue with DP, in fact I just bought one to replace my non-adjustable Dtronic (UniChip). However I would have expected a little better from them than this Facebook post which is quite poorly written and no better than some of the crap being slung by the other parties.
(Remember DP Chip is owned by Berrima Diesel which often put up some very good technical articles and posts) I expected better from Berrima/DP

Here's some of the things I picked out of this Facebook post:

The engine shown in the pictures is a Landcruiser V8 D4d, they have the same Denso injector issues as the 1kd in the Prado. These failures happen with our without diesel modules fitted so they've drawn a long bow there!

Fault codes, limp home mode and engine warning lights are signs that the factory system is sensing too much power for the particular vehicle

Sensing too much power??? it's a fault/diagnostic system, it detects open, shorted and out of range sensors etc.

They also increase soot loading in engine oil

?? all modules do this, rail or injector; burn more fuel = make more soot. Also poor tune is a poor tune no matter how the module achieves it.

Increasing pulse rate is like increasing your heart rate, we all know the dangers of an irregular heartbeat, and can literally give your injectors a ‘heart attack’ resulting in catastrophic damage.

Using the same analogy: A rail module increases fuel pressure which is like increasing your blood pressure.........

This is why the factory common rail system uses rail pressure to change fuel loads, so that injectors do not have to be held open longer and injectors are not interfered with.

Actually the factory ECU has control over both.

- Increased load on pistons

Nothing to do with module type. More fuel = more power = more load on the mechanicals

Increased load on entire fuel system

Same can be said for a rail style chip.

- Increased soot loading in engine oil

Been there already....

- Dangerous voltage spikes

If a module is well designed (in regard to its electronics) there should be no chance of this. But hey lets scare people with unfounded claims.

- Increased injector voltage to dangerous levels

Only to the max level the injector was designed for an the factory ECU goes to anyway. The max voltage may be reach earlier and held for longer but why would it be exceeded? an fully open injector is a fully opened injector!

Overloaded injector duty cycle resulting in premature injector wear and failure

And increasing rail pressure doesn't??

- No Use of factory vehicle safety systems

Hmmm... a rail chip increases fuel pressure at the rail by intercepting the rail pressure signal to let the ECU think it's lower.... the only protection is the mechanical bypass valve.


So poorly written at the very least and drawing a very long bow indeed.

One of the most respected tuning modules on the market and in fact the one most recommend by users of this forum is the Steinbauer one.... it makes it's gains by altering injector cycle, not by increasing rail pressure.

My advice to people is to research, research, research.... educate yourselves before spending you hard earned. Don't believe all the sales driven smoke and mirrors.

Thanks for taking the time to write your post Mick. Very informative!

Good stuff Mick. I read the article yesterday and was left very disillusioned with the source. I don't know if I should be concerned that the author may actually believe was was written or insulted that they think I would believe it. Prior to reading the article I would have list Berrima Diesel as a reputable source of diesel engine information. But based on that article I think I need to reassess that opinion.
