Engine/Transmission (1998.5 - 2002) ETC calibrations and performance

[jwilliams3]

From memory here,

215 hp Auto (which I have)

235 manual

235 auto

245 manual (torqus maximus program)



These are ETC engine calibrations that I know of.

Which one of these when installed with a fuel delivery enhancement box (ie TSTPM3, Edge Comp, Blue Chip FMS) will provide the most horse power (box only of course) at any given rpm? most torque? most continuous torque band?



Lets also just say that the timing impaired box users have piggybacked an Edge EZ or some other timing box to make it comparable.

Once again this is not a war of boxes, because I believe that you can only do so much with our little VP44's (and all the boxes are putting out about the same amount of power)



Just another thing I was thinking about!



And if anyone has a rare "Chapple" ECM or had someone flash an industrial program onto their ECM, chime in and let us know how it works with a fueling box attached!



All feedback appreciated!

I feel the 235 manual program is best. The manual program idles smoother at idle when you have huge injectors compared to the auto program. I had the 245 t-maximus program and when the PM3,EZ, and ecm all worked together I had too much timing advance and dyno results showed it actually affected my hp.

I now run the stock 235 manual program, TTPM set on timing only, and PM3, and you should see this absolute flat and loooonnnggg torque curve my truck has... the graph looks flat and long like the picture you would see in the dodge sales brochure.
