Toyota Diesel Prado Costa RIca O2 help?
Hello
I am new to the forum and am in costa rica , planning on running an 11 plate dry cell unit in my diesel prado with the 1kz-te engine , with research i cannot find an o2 sensor or map sensor . i have read about a chip for the ecu they sell in australia to boost hp. This chip modifies the signal to the injector pump to gain horsepower and claims that the 1kz-te engine does not have a closed loop o2 sensor to adjust their modifications made by their chip. i figure it would work the same with the addition of hho? may i be lucky to not have to make an EFIE or MAP adjustments?
Also this engine has an aluminum head and with the added combustion from the hho i am a little afraid of damage.
should i be worried of this ?
I truly belive this will work but am still new to this.
Thanks
Diesels do not need to be leaned out.

Other wise you will have to control the amount of HHO for the stock setting and settle for smaller gains. Here is something that might help you. This might not be your engine but the sensors will be similar.

There is absolutely no need to play with your fuel delivery in a diesel. A diesel engine almost always runs lean.
The addition of HHO affects diesel combustion differently than in a spark ignited engine. The combustion theory is different. The HHO effects are different. The controlling mechanisms are different than in a spark ignited engine.
