Super Sport Revo TUNING INSTRUCTIONS

Please read carefully!

The SSR provides just one base performance software that takes care of all the limiting

factors like the speed / RPM / Torque & boost limiters. Then the customer will need to fine

tune the injection duration, injection timing & rail pressure to the truck's needs.

In order to allow the customization of the performance software to the particular engine's

needs the SSR provides 50 levels each for the following parameters:

1) Low Load injection Timing ( LLT )

2) High Load injection Timing ( HLT )

3) Low Load injection Duration ( LLD )

4) High Load injection duration ( HLD )

5) Low Load Rail Pressure ( LLRP )

6) High Load Rail Pressure ( HLRP )

LOW LOAD Range : a few tips how to proceed with the fine tuning.

As a foreword for the low load settings.

Everything in the low load range can really be done simply testing on the road. Keep the

low load smoke in check, keep an eye on the EGT's and listen to the engine that's all

that's to it.

Low Load Duration is about smoke on the road ( you want as little as possible ) and spool

up for the track. Too much fuel will not spool the turbo. Not enough fuel will do the same.

Find the happy medium.!

With excessive low end smoke adjust the LLD down ( numerically lower LLD settings )

until the smoke is minimal or possibly completely gone. Find the right balance between

smoke and throttle responsiveness.

Listen to the engine for eventual combustion noise ( often referred to as “timing rattle ) and

adjust to the best possible combination of EGT's / low load smoke. As a remainder,

injecting the fuel too late ( numerically lower LLT settings ) makes for a sluggish &

unresponsive engine.

The Rail Pressure settings in the low load range have more to do with a little better

responsiveness of the engine rather than with all out performance.

HIGH LOAD RANGE tuning instructions .

To get the most out of your engine you NEED to dial in the right settings on a dyno!

This is especially true when it comes to the injection timing! While with too much

injection Duration what you get is less power and higher EGT's, with fuel injected

too early aka HLT set too high, you can ( NO! You WILL ) destroy your engine!!! One

more time, to find the right high load settings for YOUR particular combination of

modifications you
NEED A DYNO

!!! Period.

Step one : Start with dialing in the HLD.

The Duration : as a rule of thumb, every time it smokes you're loosing power and / or the

ability to spool the turbo(s). The old thinking “ if it doesn't smoke, it makes no power” is no

longer valid for the electronically controlled engines! At most, a light brown / grayish haze

is what you want.

On the dyno, start out with the HLD set to “20”.

This will provide a “base” run to compare to your further results.

Now increase the HLD to “ 30 “ and compare the dyno graphs. Did you gain or loose

power? Did the power band become broader? (Or in other words, have you gained power

in the high RPM range?)

1) Power was gained : set the HLD to “40” and proceed with the next run.

2) Power was lost: set the HLD to “25” and proceed with the next run.

Case 1) HLD set to “40 “ did loose power. Do the next run with the HLD set to “35” and

continue testing from there. Adjust the levels until you've reached the best

possible power

Case 2) HLD set to “25” did gain power compared to the runs with “20” and “30”. You most

likely found the happy medium. Eventually try a little higher and lower settings

and compare the results.

Step two : dial in the HLRP

The higher you set the rail pressure then more fuel you will get through the injectors for a

given time. In other words, depending upon the size of the injectors you may ( or not ) see

an increase in power output. If the injectors are real tall or not matched to the air flow of

the turbo(s) then all you will get increasing the rail pressure is more smoke. As said before,

smoke is less power.

At first, proceed increasing the value by “ 10 “ ( i.e. from 20 to 30 to 40 ) and compare the

findings on the dyno graph. At some point, increasing the RP further, you will no longer see

any power increase. Of course, it is pointless the increase the RP any further then.

Step three : dial in the HLT

The timing is

Over advance the timing too much and the motor is going to suffer in no time! Typically the

dyno runs do not last long enough to damage the engine even with and over advanced

timing. That makes it somewhat save to test the timing on the dyno.NEVER EVER run the
MOST CRITICAL for the performance and engine survival !!!
truck on the road or track with too much timing advance!!!

On the opposite side, not enough timing will kill the performance.

Or in other words, if you really want to perform...

YOU NEED THE TIMING SET RIGHT!
