Detroit S60 ECM adjustments...

PDI Has a dealer in just about every state in the North East...

 

Is that a DDEC IV Series 60 in that '98 Pete? If so, then dumping the wastegated turbo and freeing up the exhaust flow is the order of the day. And driven properly, increasing the HP and torque will NOT negatively affect the driveline components. The key here is "driven properly".

I am an advocate of the ECM upgrade options. But one cannot just drive it like a muscle car on saturday night with the head cheerleader in the passenger seat. To quote someone wiser than me.... "increased power demands increased responsibility" But those ECM upgrades really do not do justice to what one is wanting to accomplish without also taking physical components into consideration. For instance, putting on a ported and coated exhaust manifold, dumping the wastegate turbo for a larger T6 housing turbo (Borg Warner 171702 my personal favorite on Detroits above 425 hp), and getting rid of the stock OEM mufflers for something like Walker Megaflows, will do more on their own to increase efficiency, and combined with an ECM upgrade, they really bring out the best in that upgrade. Those physical components will increase the exhaust flow by over 200 cubic feet per minute, decrease EGT's by a couple of hundred degrees, and allow more of the engine's power to be used more effectively, instead of trying to push the exhaust out. Those mods have a good return on investment. Usually within 6 months.

In many instances, following the "driven right" principle, these mods in combination can easily equate to 1 full mpg better, and 1/2 to one full gear less downshifting on hills. There are many people I know that have gotten into solid 8 mpg territory doing all these mods in tandem. This has been proven. You can't just set the cruise and run it. You have to watch the boost and pyrometer gauges and drive the engine right. But the reward is worth it.

His shop has been dedicated to the performance of
the S60 since the 80's I believe. They have MULTIPLE wins, trophies, and records.
Of which they are most proud of the wins/ records in "CAT COUNTRY".
Dyno contest in Emporia, I believe, where one of Eric's 12.7's put 1300hp+ to the ground!
Oh, and that's a daily driver, if you were wondering. It is turned down on the street when worked.
Any DDEC I-V owners want power, mpg's, and a CAT draggin Detroit, this is the guy!
