MUMSRIG..... need I say more

Thanks for the feedback on the solar input... mine is 120watts so I never had a chance to check......
On the subject of the Chip-IT... I put one on my 120 a couple of years ago, and it was initially great... but the longer I ran it the more knocking and worse fuel consumption I got... I was looking at new injectors when the mechanic said try it without the chip .. so I unplugged the chip and ran the bypass plug... OK, down a bit on power but car seemed much "happier" (smoother and quieter etc). Eventually I pulled out the harness and put the lot back in its box. Car has been running well all thru last winter's cold...
I think that the D4D just can't handle the extra fuel rail pressure.
I ended up not even replacing the injectors - but am sure that day will come.
So if you want the chip, one with std fuel pressure looks the way to go.

Ours is pre-common rail and simply provides a regulated voltage to the spill valve. This 'regulated' is the issue in my opinion. More fuel but nothing else gets adjusted to compensate. Hence higher consumption and higher EGT's.

I just wish Diesel Care had fitted the Steinbauer and removed the ChipIt like I originally asked instead of finding all of these other so called issues. All my concerns were based on the ChipIt.

I don't have a chip but I reckon mine is spewing out unburnt diesel as my fuel economy is rubbish too. Will need to get it looked at in a couple of weeks

I don't doubt that there are vehicles out there with injector and injector pump issues and depending on your kays getting the injectors serviced every 100,000klms is probably a good thing. Hopefully it's something simple for you.

Hi all, I thought I would update this thread with some info regarding the current status of MUMSRIG regarding power and torque output.

Standard with 3" mandrel bent exhaust and muddies plus a uni filter was 48.3kW@tw with 254Nm of torque

When the ChipIt was installed we ended up with 67.2kW@tw with 346Nm of torque at 15psi of boost


With the addition of the new Injection Pump, Injectors, rebuilt and Hi-Flowed Turbo, K&N Filter and the Steinbauer and with only 12psi of boost we netted 63.8kW@tw and 655Nm of torque


I'm going to install the lockup torque converter modification so we can ramp it up a bit better on the dyno and play with the Steinbauer a little more as it's just been left at the 'out of the box' setting and can be adjusted by the dealer through the laptop so we can get a bit more grunt.

Overall MUMSRIG feesl a lot better, power delivery is much smoother and i don't need as much throttle to get it going anymore. It cruises much more efortlessly and it looks as if the fuel consumption has improved a little. I just filled it up again so will see how we go with this tank before I jump for joy LOL

Fingers crossed Mitch. Mines going in Wednesday to get looked at.

655Nm torque. VERY impressive Mitch. Gotta be happy with that!

This caught my eye too Craig, look out 4.5L V8 diesel toyotas!

Typo me thinks...

Have a look at the dyne sheets I attached.. No typo

300Nm increase in torque but a minor drop in power, something is fishy there. Possibly the dyno runs have been done in different gears, skewing the torque result.

Bingo Leachy.... I was waiting for someone to catch on

Apparently the dyno never lies LOL

This is the reason I will be fitting the torque converter lockup mod so I can utilise it to hold the gears without upshifting with a minor mod... Bloody autos

Wifey has decided to keep the Prado. 1x less bill we will have to worry about each month if we had replaced it!

Good decision I say!

Hi all,

It's been a while since I've done anything to the old girl and today I upgraded the dual battery system's DC DC set up. A while ago I installed a CTEK D250S along with the Solar Panel however I wasn't seeing the results I was after as I was having to continually charge the 2nd battery as it wasn't getting enough from the CTEK. I did a bit more investigation and found that if I added the CTEK SMARTPASS to the D250S then it would favour the 2nd battery plus the output would be higher and help charge the batteries quicker.

I installed it today and did a few tests. It's definitely the answer to my problem! It controls the system much better now!

Here are a few pics.
