1uz vvti crank and cam pulse count

**dumbass** · 13-04-2013, 03:51 PM

hi all does anyone know how many teeth or pulses per rev on crank
and on cam for a 1uz vvti

i dont have an engine wired up in a car to test so im going to make a full bench testing harness
so i need to know what pulse count to put into the ecu to get it to fire the injectors

i know its different to the non vvti 1uzs

thanks

ok thanks
next step is i have to find 2 more of these vvti ecus to buy
shops around here dont knwo where to get em from

be sure not to buy uzs157/4wd and uzs175 ecu's as they're a bit different in pinout

ok cool
ive got one ecu and managed to get chip to turn off security led
but i still use key reader
next step is to flash ecu to need no key reader but i got no engine to test it on
so i have to try make a bench loom with crank and cam signal and injectors and coils
hopefully i can get by with some noid lights and hopefully the security light still works
even with no key reader i hope to get it all working with just the bare loom
but i really need a std running enigne to properly test it on
just there is none around

Your only way is uzs155 ecu which have no immo (1997-1999, pre 97 is different pinout). This ecu does have the same memory chip as found in later ECU's but its content is nonsense, and it doesn't turn immo off in later 1UZ ecu's

To turn immo off I fabricate bypass devices that simulate key+antenna+reader. The solution is straightforward, if you know how to program a key into memory chip and have a look at data interchange between ECU and reader.

i just did it to try crack the ecu
but for now its easy to just get some 2nd hand key readers from friends in japan then program some transponders to it
now ive sorted that next step is to try to turn immob off if possible
there is not enough demand for vvti 1uzs here so im not doing it to make money
im doing it for learning
thats y im trying to get afew more vvti ecus for practice
should be able to do it for couple hundred bucks if possible

I have no such friends unfortunately, so as I started to do more than 1-5 vvti 1uz's per year I felt the lack of amplifiers available at reasonable price. Besides as I made my bypass device available for sale as part of immo disable service, I began to receive JDM ecu's of other types (2jz-ge, 2jz-gte, 3s-gte). I quote around 200 total for work+materials. Parts for the device (including PCB, when ordered more than 20 at once) cost around 5% of the price and I'm independent of the supply of amplifiers.

btw many toyota amplifiers do fit 1uz vvti, for example corolla ones. You only care for transponder compatibility.

over here its hard to do it for 200 bucks
i would just want to send them your way
i want to concentrate on getting it all working without needing any other stuff
just reflash ecu chip
i doubt ill make much money from it as ive only got one or two emails or phone calls lately to bypass security
i just bought afew more scan tools to do more diagnosing of late model cars
aswell as wiring up couple hundred motors each year
