here are the untouched maps as they came from vortech, kinda weird, hard to make sense of how to adjust.

fuel close up, see how the fuel is adjusted at weird boost levels, they have something going on in the reading settings

Dyno sheet from map above from VORTECH so you guys can anylize and tell me what I should do!!!!!!!!!

Is the boost PSI listed there based off absolute or is it differential?

Reason I ask is because I don't see any timing adjustments until 8.5 PSI. If that's the case then people running the stock PSI levels aren't getting any timing adjustments from the stock maps.

System Settings are:

Display Mode: Gauge Pressure

Application: Additional Injector Controller







Output settings are:

PWM Mode: Pressure to 30 Psi /5 vdc FS

Output A Mode: Aux Fuel Pump with abortive start time

Output B Mode: Over RPM and Pressure

Output C Mode: Inj A and B over /latched



Over RPM: 500

Over Pressure: 8.1

Over INJ %: 0

Fuel Pump start pressure PSI: 0

Fuel Pump run time: 0

Fuel Pump startup time: 0

K thanks. So now the question is, why do they even have the SS box if it's not retarding timing at stock PSI levels? I mean it's nice that they included it if you go to 8.5 PSI, but if you're running the stock boost levels, it's not doing anything.

Vortech also claims that the SS box doesn't control fuel either. Oh well, just trying to understand what the SS box is doing.

Look at it again my freind..............

OK, I've looked at the timing graph 10 times now. The first time I see it retarding timing is at 8.5 PSI @ 5000RPM

Clue me in, what am I missing?

wut's ur 1/4 mile time?

fluidz

The first thing i notice is that it based on Gauge pressure and not Vacuum/Pressure and it starts to read at Over pressure 8.1


Change the settings to Vacuum/Pressure and set Over pressure to 1 and the numbers make sense.

Basically its pulling 1 degree at 5,000, 2 at 5,500, 3 at 6,000 and 6 at 6,500 under 7lbs of boost over 7 lbs of boost 6,000 rpm jumps to 4..........8 degrees dosent come in to play untill you hit 9.5lbs of boost, safety feature in case peeps change pulleys i see!!!

fluidz

well now I can see why enthuzed got 393rwhp...........less timing being pulled and right around 12.5:1 A/F untill he hits 5,000rpm then he dumps fuel to bring it down to under 11.5:1.............very interesting.

fluidz

going to the track this wednesday....i hope!......

Your way too rich for one, tuned yet? Let me know on Wednesday I will go, it will be hot though like 80's.

I certainly wouldn't recommend taking out less timing than the out-of-the-box program! My suggestion for A/F is 12.0 from 3500 to 5500 then drop to 11.5 @ 6500 rpms.

fluidz

what about changing the 5,000 to 0 on timing ..............its only 4.4psi??? and at 5,500 retard 1, 6,000 2 6,500 6???????

350zer

for one 393 rwhp is on 93 octane. i hope you are lestening real close because my car pinged right around 5000. i took out another 1 degree. i don't no how much you guys really know how this box works. at 100 rpm past any cell it is looking to the next cell. example, at 5100 rpm the box is reading what number is in the 5500 rpm box. if anybody wants info on box give me a pm.
