Let this be the final and last thread on these two items that usually
BPU supras use!
# Greddy Boost Cut Controller
As you can see the late edition Greddy BCC is made for specific JZA80
supras! There is no more BCC for MR2 SW20 which could be used on JZ
series.And there isn't an adjustable switch/knob that can regulate/tune
the preferable boost cut.With the old BCC device you had to tune to about
4.1 or 4.3 Volts before it's installation.
I think that the absense of the tuning device on the new
BCC is because now it is made specific for jza80 2jzgte motors! And it sets
the boost/fuel cut at the limit of the MAP sensor which is about
1.15 bar (16 psi) on JDM engines...
My 2jzgte is from Aristo car and is a JDM motor,so it will work fine....I think
it will work on USA and export models to...I don't know for sure.
The Red wire is +12V ,the Black is Ground and the Green & White go to the
MAP signal wire... pin 62 on the TCCS ECU plug,so installation remains the
same as the old device!
# Greddy Speed Limiter Cut Controller
Now the speed cut controller makes me nervous...
It has 5 wires: red is +12V ,Black is Ground OK....
But there are 3 wires more to connect! 2 of them go to the cut Pink (speed sensor wire)...and remains 1 wire to connect
Searching the net I found that this wire is probably the 'Blue' one and it
will remain off connection.
Please post your thoughts and your knowledgment on these parts,so
people can get first class info about the installation and the operation
of these units....
