Hi guys.
I spent some time chatting with a friend who is a trained Toyota mechanic and the conversation drifted around to running chips to gain more power.
He said that he has replaced some five or so high pressure fuel rails in Toyota diesels as they had cracked he believed due to the chip having programmed the fuel pump to deliver more pressure into them than they are designed for.
It seems the chips are programmed to increase the fuel rail pressure in order to force more diesel through the injectors for the given time they are open thus providing more power.
On the strength of that, when choosing a performance chip consider the above and seek one that does not over boost the pressure in the rail but programs the injector timing to stay open longer.
I say that without knowing a great deal about how the chips are programmed
He mentioned also that he has seen some vehicles come into the workshop running in 'limp mode' as there has been an electronic conflict with the chip and the vehicles ECU.
He has experienced this himself and has removed the chip in question from his Hilux.
I don't know the brand of the chip he was running.
Has anyone experienced the above and what was the outcome?
Let us all know as while we read how good the various chips are but a word of caution, they are written by the promoters.
Having said that, I read a number of comments from satisfied customers who love their chip due to the performance increase they gain.
Cheers guys.
Graeme
