if i understand with this chip the car is in full power all the time ? even if one of parameter too have the full power is bad ?

ugo,

With the secondary delete option as Marc does it, you are always on full power. No other option. The parameters that would disable FULL POWER on a stock motor should be eliminated ie Not enough vacuum etc. In fact Marc programs it so that you would not get a code for insufficient vacuum. If you have a bad injector or insufficient fuel, you'll get a lean code 61. In that instance, sometimes the SES light will flicker and not be a "hard code". No matter you don't want to run the car very long.
As an FYI, I originally removed throttle plates and tie-wrapped the secondaries open. I also installed a "dummy plug" on the secondary MAP sensor. ECM was happy.

I had a bfxbg for 91 ,i remove secondarie,change injector,fuel pressure regulator,fuel filter,fuel pump,spark plug and wire, oil temperature sensor,o2 sensor,ECM .I test MAP - coolant sensor- knock sensor, i looking for restricted air flow, i test the harness of injector and every sensor inspect connector !!! Today i drive with a fuel pressure gauge atach to windshield, it's varie about 40-50 psi....normal! but no full power and always code 61 and 55 !!!! i'm going to burn this car!!!!

On my 90 z, I bypass the full power key to always on! I do this by splicing a wire into the #9 blue & white wire in the green micro pack in the ecm, which is the hot wire for the full power key. Then I ground it to the frame. This way I did not have to mess with the key! loose key! bad key! and the light is always on!!!

My performance calibration chip BFXBG enables the Full Power mode when the engine starts. The green light next to the Full Power key will go on when the car is started.

If the engine control system gets an error that sets the Check Engine indicator on, the system will not operate the secondary port throttles even if the green full power light is on. The fault that causes the check engine must be corrected to operate the secondary ports and get full power.

When does the check engine light go on? If it goes on what is the error code?

[Marc Haibeck]

If you are using a chip labeled as BFXBG the secondary port throttles must be working normally. If there is a low or high vacuum fault in the secondary control system the engine will get a Check Engine code 61 when the main throttle is opened enough to trigger the secondary ports.

The chip needs several modifications to run without secondary port throttles. If the chip has been modified to run without secondary port control it will be labled as BFXBGxx. Where xx are the inititals of the name of the person that purchased the chip.

I think the problem is.......me !
I don't understand (i'm french...) how work the chip bfxbg when i buy it I don't have the good version for run without secondarie !!!!!
I can 't tell you the reference i'v got today,but i look for tomorrow.

With no trouble code store (i erase before with tech1) ,valet key in full code 61 and 55 come. No cut out.Some week before i got a litle misses at 5000 rpm,but now run "normaly"

thank mark ! Saddened to have made you waste time
I will contact you on your web site....

Marc modified the program of my chip and now......my z run very very well !!!
