what would be the best settings for the mallory box??

im running a 100 shot plus everything in my sig

my computer is redlined at 6600 and the shiftpoints are at 6150 (A4)

soo far i have the window switch to open at 3000rpm and to shuttoff at 6100(should i go lower?)

im just confsed about the rest of the settings, Ie: wich setting do i used for the timing retard and how much ?

Most seem to agree to remove 2 degrees for every 50 shot. Seems like the yellow wire is the retard function? Is that what you're asking?

im asking about the settings on the box, they are listed 1-8?

i know 4-5 control the window switch , im just asking what other run on each of their settings, i know a few i dont have to use, but which setting do u use for the timing retard. There are few that use a retard function , one for ignition/starting and there are others.

Honsestly i havent gotten to in depth with the directions which i shall do later , but im just interested in cing how other ppl run their settup

Make sure your Hyfire RPM limiter is lower than what is set in the PCM (ECU) otherwise you will hit the latter before the former. The advantage of the Mallory limiter is that it cuts spark rather than fuel like the factory setting in the ECU. As for the RPM window, unless you have some internal engine modifications, I would set the high to several hundred rpm before the rpm shift point. I have my window at 3800 - 5400. I am pulling 5 degrees on a 125 shot because I have a tune in the pcm that has advanced timing slightly. If you don't have a tune then 2 - 4 degrees is plenty; some run a 100 shot without pulling any timing at all.

yes i though 50 rpm for teh window swtich to go off was pushing it , i will lower it as soon as i can test drive it

right now i have the rpm limiter (mode1?) set to 6500 which is 100 less than my stock is, is that ok?

as for the timing retard, which mode do i used, i belive it was 3 or 4 i dont have the directions at teh moment. i shoudl take about 3-4 degrees out for it? alos i believe it said timing is is adjusted in incriments of .1 , hopefully that doesnt f-me lol

i have one myself. i THINK i am using it right.
MODE 3 looks like this. 5.0 3 <<< the 3 is mode 3 and the 5.0 hopefully means that the timing is retarded 5 degrees.

on a 150 shot with the setting at 6.0, my exhaust pops and the car dont run right. with the timing at 15.0 ( the most u can go back) the car barely moves.
with it at 1.0 ( i assume that is the stock setting) it runs alot better.
keep in mind i am having issues on the bottle, so i assume this is not the same as everyone elses.
just figured i would throw that out there so u had more of an idea.

let us know what works best for u.

You need to wire up the timing retard so it only pulls timing when the nitrous is spraying. I hooked up the wire to the power side of my nitrous solinoid.

camzaro28

yeah i did that yesterday. got er done. but havent used the spray since to see if it helped.
do u think that was part of my problem?

CamaroSS30thAnn

well im getting my bottle filled today and im gonna have my tech (friend) work it out for me and do some test runs

hope everything is set up right


thanks for the info ill make sure i take away some rpms on teh window switch and pull some timing.

they have everything set up on a relay so when i click teh button teh relay hits the window switch and hoepfully the retard lol

thanks for the help

camzaro28

let us know what happens!
have fun

how did it go?

CamaroSS30thAnn

well i race a buddys ls1 t/a of mine n/a. we should be at teh same power output or close to

he pulled my by about ~2 cars i was dissapointed

then i did a nitrous pull i beat him but i didnt pull hard at all......it was a cold night and i dont have a bottle warmer so i think that may be a problem

i do not know but i want to get this nitrous issue figured out

i have the timing on the box set at 4 the window is 3k-6k

i know the n2o works cuz i beat him on the seconnd run but i didnt pull hard at all , prolly only beat him by like 2 cars

100 shot shoulda made a world of diff

camzaro28

well you made up @ 4 car lengths. seems about right, maybe a lil on the lower end.
no popping or anything? just pulls right through?

CamaroSS30thAnn

i did not notice any popping and i have my mode 3 selectable retard set at 4 degrees

yeah i did make up 4 cars but i dont think its running correctly i should have pulled harder

o well i have my buddy check it out as soon as i get a chance

maybe ill just throw in the 125 jets
