DP34, DP chip for the 1KZ prado

[Tony Ellen Lurker Find all posts View Profile Close Tony Ellen]

Hi,
I'm chasing a copy of fitting instructions for the DP34, DP chip for the 1KZ prado. I've purchased one second hand and can not get any assistance from DP Chip without returning the product to DP Chip at a cost of $170 for an unnecessary recalibration. Considering the cost of the original purchase, I can't see the justification for them just to "double dip".

Re: DP34, DP chip for the 1KZ prado

The DP34 chip is a generic chip that will suit multiple vehciles. if this was NOT in a 120 1KZ Prado then the flash program on the chip will not suit your vehcile. It may provide improved power and economy but it may not. The $170 would cover the cost of putting the correct flash progam onto this chip as well as testing the chip for potential damage. If you know this was on a 1KZ Prado then you don't need the chip reflashed.

Re: DP34, DP chip for the 1KZ prado

I cant give specifics but in general you should have the box a plug and 3 wires coming out of it.

The plug goes over somwhere near your injector pump
Positive and negative wires to the battery
The third wire is spliced into into the electronic throttle wire on the car this is why the DP chip will not work when the cruise control is on as it needs to know the throttle position and it cannot determine this with CC as the computer takes over

thanks chester,
my chip (dp34) has 4 wires coming out from it, grey, brown, red going one way, while a white wire (which splits into a brown, and a black sleeve over red) goes the other way in the harness.
appreciate your response

Hi tony

I have a set of instructions here if you need them i can copy and post or scan them and email them to you just let me know whats easier you will not be disappointed witht the change though i have noticed my fuel consumption is up a bit i have lost about 100ks per tank. But the power more than makes up for that Let me know if you need it but i agree with schaffer if its not configured to the prado it could end up messy but happy to give you the instructions i just take no responsability.

Hi Craig,
I'm confident the chip came from a KZJ 120 series Prado, the previous owner still had the vehicle for sale in the yard when I picked up the chip. I would be stoked mate if you could scan and email me a copy of the instructions, I'm heading off to the beach this weekend and would really like to see if this thing will provide the extra power, particulary when towing. (Address is [email protected]). Thanks for the help.

I was very interested to hear that the DP chip will not work when the cruise control is on. Could you please confirm as this would defeat the purpose (in part) as it would not be working on a long trip using cruise control when ascending hills.

If you want the DP Chip to work while using cruise control you can attach the grey wire to the centre wire (Signal Wire) on you MAP Sensor, The only problem being on manual vehicles you may get slight overrun on gear changes.

Hi Craig,

I have just bought a second hand chip as well and did not receive instructions. No where on the web can you access instructions for installation. Would you mind sending us a copy of your instructions as well?

Thanks, Paula

G'day Tony. Did you sort out your wiring with the DP34 chip? I have just bought a second hand one from Ebay for my 90 series Prado and it has the instruction card with it. It's a bit vague (or it may be me that's vague) but if you still need the info I'll send it through to you.

Hi Craig.
I'm in the same boat as the other guys, bought through Ebay, a second hand (used) DP34 chip, removed from a Surf with the same 1 KZ-TE engine as my 90 series 2002 Prado. The package came complete with all installation instructions for the surf, but the ECU and the injector pumps are different between the two vehicles.

I have worked out the appropriate connections to the four plug ECU on my Prado, transposed from the three plug instructions for the surf. However the connection to the injector pump signal wire has me a bit tricked. The photos in the original instruction card are very vague. It appears that the white wire from the DP34 harness connects to a red wire entering the injector pump, but the set up looks quite different from my Prado.

Could you please look at your installation instruction card and let me know which wire into the injector pump I need to tap into. Alternatively if you could scan and email the instruction sheet to me, 'twould be even better. [email protected]

Thanks in anticipation.

Gentlemen.
I have followed this thread with interest since before I purchased my used DP34 chip on Ebay. The unit I bought was removed from a Toyota Surf, prior to resale. It was installed in the surf in 2008. The reason I bought the chip is because it is set up for the 1KZ-TE engine, the same engine as in my 2002 90 series Prado.

However the installation instruction sheet that was included in the kit was for the '95 Surf and it is quite different from my Prado. The surf has a three plug connection to the ECU whereas my Prado has a four plug connection. Also the connection to the signal wire at the injection pump looks, from a very vague photo, to be quite different from the Prado injection pump.

I have sat down with the installation card and my workshop manual and worked out a transposition from the three plug Surf ECU to the Prado unit, all good and tested for OK. However the connection to the injection pump signal wire has me a bit baffled. In the diagram (photo) it shows the connection to a red wire, adjacent to a blue wire just short of a plastic plug. I have located a red wire, adjacent to a blue wire into a plug into my Prado injection pump, but I'm uncertain as to whether it is the correct red wire. Can someone please tell me if I'm on the right track here. If this assumption is correct, I'm very close to enjoying the benefits of my new (second hand) DP34 chip.

Thanks in anticipation.
