series 60 programming only!

**amishmafia00** · 11th February, 2011, 05:35 PM

I would like to have this thread for posting how to make the series 60 run better using dct. anyone who has experience tuning these engines please post what things you changed and what results you had.

Please post questions about installing dct to this thread

dct quick refrence: lots of good information on dct

try going to the start menu/ all programs/detroit diesel/ calibration tool quick refrence
if this doesn't work go to c:\program files \detroit diesel\calibration tool\ WCT.hlp

advance the camshaft timing helps tremendously!

can you explain how to do this? just learning how to use ddct and would like to learn all i can.
Thanks

you can play with cold advance timing if you change the gear of the cam in the front cover of place the engine is not build for that you cannot play with the timing of a detroit beleive me
the piston are very close of the valve if you play with timing the valve become more close and with hi rpm everything broke

**ddmech** · 9th March, 2011, 07:29 PM

to change the timing without danger you must have gauges to check advance.we have advanced a tooth numerous times and still be in ddc specs.

**ddmech** · 9th March, 2011, 07:33 PM

ps. sorry but I dont dont know how to do it with dct.Someone else might though.

ive seen a couple of different cam gear hubs. most ive seen have no adjustment but i changed cam in a ddIV htat had a adjustable hub. anbody have part #'s or insight on this?

**ddmech** · 14th March, 2011, 08:17 PM

rebel is correct.Gears are not adjustable.We make offset timing pins to advance our camshaft timing.This is not detroit diesel procedure.Tese are custom setups.Tricky but very effective for power and economy.

why not just play with timing map in ecu?

just my 2cents,but that only works on injection timing,not valve timing...
which may or may not have an effect on fuel mileage and power,but i wonder how much can be gained by playing with injection timing alone...something to think about.
If anyone has any thoughts or suggestions on this,please,speak up...the masses await.

injection timing does make a difference but i completely agree it makes absolutly no difference to cam timing one bit and people playing with the stat of injection should be carefull because advancing it too far without changing cam timing will cause the injector valve to open before the plunger starts to move so the plunger does not have enough time to create the nessasary preassure to rappidly open the nozzle as required for proper atomization it will drip fuel at start of injection and then opening the pulsewith from original start of injection can cause the injector to remain open over the nose of the cam which makes the closing of the nozzle to dwindle away instead of a rapid shut that will drip fuel at end of injection that may build up on top of piston causing engine failure

I just wonder how far one could go...anyone ever played around with this?
I do have a calibration in mine now that is 550hp@1850ftlbs,the only difference i can find is in the BOI and Pulse width tables,not sure how much hp she is really making (without a dyno report) but according to ddrs,she is making 1850ftlbs of torque,and i sure can tell the difference...doesnt seem to have hurt the fuel mileage either,still getting 5.5 to 6.5 mpg with i 98 western star that weighs almost 25,000lbs all by herself.

i

I have probably 30 trucks out there with this done to them,and it is a proven fact it helps power and economy.It does change vale and injection timing to an extent.Changeing timing in computer would definately help both.JJust havent tried that yet.Camshaft timing method is proven fact.

**Emgo** · 15th March, 2011, 05:36 PM

The timing that is controlled by the ECU is the injection timing called BOI (beginning of injection) in DCT. It's like ignition timing in a gasoline engine. Cam timing is something very different. It is a mechanical setting and I'm reasonable sure it's not changeable with the ECU in a series 60. I have degreed in many cams for gasoline engines. As a general rule when you advance the cam timing it moves the power lower in the RPM range and when you retard the cam timing it moves the power of the engine higher in the RPM range. I think the same would be true for diesel engines. ddmech I would like to know how much you are changing the cam timing. Are you using the center-line method? Gasoline engines will usually have a range something like 102 to 108 degree center-line. I'm sure you can make improvements by changing the cam / valve timing.

I'm very glad you started this thread. I think I see what you want to do. It would be great if there was a way to split up the existing threads on DCT, DDDL, DDRS, Cat ET, Cal Term III, etc. into 3 categories. Installing, Keys and Using the software. There is great information in all of the existing threads. I spend a lot of time reading through the threads trying to learn how to use the different softwares. I think it would be beneficial to everyone if there were a way to keep the 3 items separate. Maybe a moderator or an experienced DK'er could chime in here. At least we might be able to start 3 separate categories next time we have new software to share or maybe it's a bad ideal for a reason I haven't thought of.

I'm very interested in Series 60 performance and fuel efficiency increases whether it comes from mechanical changes or reprogramming.

Thanks,

Emgo
