i got my j&s is on and appears to be operating. i need to know how it needs to be set up. i ran it with it set like it came in and as soon as i get pass 4k rpm it takes all kinds of power away from my car. but the gauge doesnt say it is taking any timing. i just unplugged it so i could drive home with out the hassle from it, lol. i know there are boost and start knobs on it but it doesnt say how they need to be set. i had the sensitivity set to ~1/2 way. it is set on for cylinder, whole engine, 20* settings. basically the max on all i guess. any suggestions on setting this thing.[thankyou]

If you don't have J&S plugged to the vacuum line u don't need to set up boost knob....did you try to tap on your block to see if it's working and gauge is showing timing that has been taken away ?

i havent done that yet. i ran out of time in the shop. it is hooked up to vacuum.

Make sure it is working properly , it shouldnt be pulling any timing if your not seeing the Gauge go crazy and light up unless you have it set to pull for boost and you shouldnt

Hmmmm mine engine has to be super quiet as I saw only pulling like 4deg. in higher rpms (for a split seconds) on my way back home and sensitivity is on max. I'm going to tap on my block to see if everything is fine..

tls_bmx ... one question...where did u install J&S unit ? It looks like it's under your steering wheel... and first step from instalation manual :
1. The unit must be installed in the passenger compartment....

Wouldn't that be considered in the passenger compartment since the steering wheel is in the passenger compartment?

[scratch]

^^ I thought it shoud be placed closed to the ecu...liek in glove box....OK, i just did my testing...knocking on piece of pipe I run between intake manifold and engine (the end was touching block) and I was taping on that pipe with wrench....J&S was working....

yeah it is under the steering wheel and that is in the passenger compartment, it definitely isnt in the engine compartment, lol. i dont know if it is set to pull for boost or not, how do i adjust for that? there are 2 knobs for boost retard. and the gauge only did what it was suppose to when i started the car then after that nothing. i will go check to see if it is working.

i tried to check it but i couldnt get it to do any thing. is the gauge suppose to do any thing at idle because mine isnt doing any thing. i dont think my gauge is working. my light is flashing on the j&s at idle but not the gauge. i tapped on the block the best i could reach with a pipe and had the vacuum source off and it held at 2k and set it on max sensitivity and it didnt do any thing. i will try it again tomorrow when i can get it on a lift and actually get to the knock sensor. the gauge does light up and everything before i crank the motor but as soon as i do it stops. i got it to stop bogging my car now. i reset the boost start and rate.[?|]

and as soon as i unhooked that vacuum source the idle smoothed out and it started trimming the fuel.[dunno]

^^^ heheh ok now I understand...that boost...based on instruction...first knob (boost) is adjustible ... 0 to 10PSI.I put mine completelly on the left (minimum=0PSI) and second one is adjustable timing retard for boost...0 to 2 degrees for PSI...I got mine on minimum 0 deg. as well..... so I think u can use those two if u have hooked up that manifold vacuum and for ex. u set up boost knob to the middle (5PSI) and second knob to the middle (1 degree) it will automatically pull 1 degree of timing per psi after u hit 5 PSI(including) ...maybe I'm wrong ;_) Won't be the first time ;-)))

yeah you have yours set the same as mine. not to pull any thing for boost

my gauge it's not showing anything at idle...and it shouldn't as j&s got activated on higher rpms... i did everything from the top...

well i thought it said as long as the rpm's are below 980 it would pulse and when you brought them up it would switch to the retard mode

Read the "test" instructions closely

i got it to work. the gauge and everything is working. i set it on max sensitivity and drove the hell out of it on the way to school. it is working. i got it to make one light and i could tell when it did.

1 light is nothing to worry about
