moregrip Posted August 6, 2006 Report Share Posted August 6, 2006 (edited) had a fantastic day yesterday working with btlfed1500 on the MP112 baseline test/tune. Understand when I refer to "we" the emphasis is heavily favoring the tuner and not myself. The goal was to optimize the current calibration/setup, basically taking a stock Radix with basic bolt-ons as far as we could while staying safe for daily driving. Some interesting things of note, 1st, while we did the bulk of our testing with the converter locked. We saw no power gained from testing unlocked, the power curves essentally lay on top of each other. 2nd, due to the 2500HD converter being considerably looser than a typical 1500 series, we weren't able to lug the motor as low as I had originally thought we might, however it was consistent at its lockup point. 3rd, 7lbs of boost. 4th, all data corrected to the latest SAE standard. 5th, fuel pressure was 63psi at idle and 63psi WOT/6000rpms 3rd gear(in tank Walbro). 6th, all runs conducted with hood closed. Max power gains over the stock magnacharger calibration are: +8rwhp, +9rwtq. However, the real benefit observed is with the power under the curve. You can see on the dyno graph the sections in the power curves that are +15rwhp +15rwtq. The net result is more usable power, sooner. I am very pleased with the final baseline results that repeatedly showed 430rwhp/440rwtq. Figuring 18% driveline loss, roughly 505hp/520tq at the engine. Just after I bought the truck in late 04 I had it dyno'd bone stock and made 245rwhp, so for a stock LQ4 Radix setup(3.1" pulley) with basic bolt-ons (LT's, dual exhaust, CAI), and a custom tune, I'm pretty happy with the results so far as I'm up approx 185rwhp.

TBSS Posted August 6, 2006 Report Share Posted August 6, 2006 I think you're losing a little more than 18% through that 4L80E...probably 20-22%. Good numbers though. Quote Link to comment Share on other sites More sharing options...
Sum 1 Posted August 6, 2006 Report Share Posted August 6, 2006 That's a 4x4? Solid! Quote Link to comment Share on other sites More sharing options...
FuelSlut Posted August 6, 2006 Report Share Posted August 6, 2006 (edited) nows all you gotta do is come up with a 2/4 band that will take that shit daily Edited August 6, 2006 by FuelSlut (see edit history) Quote Link to comment Share on other sites More sharing options...

moregrip Posted August 7, 2006 Author Report Share Posted August 7, 2006 (edited) thanks guys................are you referring to tranny durability? Edited August 7, 2006 by moregrip (see edit history) Quote Link to comment Share on other sites More sharing options...
BenKey Posted August 8, 2006 Report Share Posted August 8, 2006 What was your best with the MP112? Quote Link to comment Share on other sites More sharing options...
moregrip Posted August 8, 2006 Author Report Share Posted August 8, 2006 (edited) What was your best with the MP112? <{POST_SNAPBACK}> once we made a few jumps in power, we averaged about 430/440 peak, then looked for the most power under the curve. the two posted are the best peak, the second one posted made the best peak and best overall power and is the calibration currently loaded in the truck Edited August 8, 2006 by moregrip (see edit history) Quote Link to comment Share on other sites More sharing options...
zippy Posted August 8, 2006 Report Share Posted August 8, 2006 When you say you looked for more power under the curve, I assume you mean part throttle??? Usually when I'm doing some dyno tuning I go from about 2500-XXXX and anything under that curve are numbers I've already beaten. Quote Link to comment Share on other sites More sharing options...

FuelSlut Posted August 9, 2006 Report Share Posted August 9, 2006 the lingenfelter theory.... sorry, i just read a book by him and he cannot stress enough aboot "power within the curve etc. etc. etc." Quote Link to comment Share on other sites More sharing options...
FuelSlut Posted August 9, 2006 Report Share Posted August 9, 2006 thanks guys................are you referring to tranny durability? <{POST_SNAPBACK}> yes... unless the new radix has a 2/4 band , if so... i think i should stay the hell away from it btw nice A/F there...

moregrip Posted August 9, 2006 Author Report Share Posted August 9, 2006 forgot to mention, these runs were with my 32" tall tires on 20x10 wheels Quote Link to comment Share on other sites More sharing options...
