cloud n it is my brother
I have done some tweaking with MCC for this truck.
To recap on the truck. Full deletes, egr delete with elbow, and 5" exhaust, arp studs, MPD install kit for single, BW S472 reg cover 71.1/83/.9/T4, Mini Maxx
USED HD300 as base tune with S1M trans schedule
With the few tweaks i have done, we now have cruise, no DTC codes now for turbo or related and a lot better spool up. I delayed up-shifts to help build boost / rpm and truck pulls hard now through to OD, delayed it from shifting into OD until boost is fully up, right now peaking at about 42psi of boost
I have altered the fueling as we want the truck to run clean as a daily driver.
In town driving and general mid throttle acceleration lag is very minimal compared to stock, albeit requiring higher rpm/delays shift.
From a dead stop truck smokes moderately under WOT from stop until truck has just shifted into second and boost has came up to about 27 psi and then truck runs clean until torque convertor locks in third at about 34 psi and briefly smokes until boost catches up which is very quickly and it runs through to 4th at about 42psi
Looking for tips in general and things in MCC:
People are welcome to throw me under bus but the more that are willing provide their own input on this and helpful suggestions for MCC the better.
Questions to start, once some people chime in there are more to follow:hammer::hammer::hammer:
1. what rpm should i look for max for WOT shift points, at each shift point,
2. i have not altered T/C TCC settings at all, down shift points are similar to stock and i set the values in the settings over 75% throttle to down shift sooner, this helps it stay in the RPM range where boost builds quickly / less lug and less smoke, with the box tune S1M the truck would drop low in 4th with TC locked and anything more than slight amount of throttle would mean MEGA smoke, truck now drops to 3rd and lights quickly, locks and goes to 4th with only moderate smoke on T/C lock. without altering any tables but shift points, is this hard on anything and what is suggested, trans is stock
3. by using HD 300 and altering the smoke limitation tables only to find spots where fuel could be added, is that a safe method, with the theory that HD300 has very good timing/volume for fuel settings built in and limiting where that fuel can be delivered with the smoke limit tables is it correct to think that means it is using a proven fuel map and just overriding it at all points using the set maximum in the limit table?
4. this is a daily driver, so although finding the fueling/shifting for power is important in the top end of the maps for WOT or close to WOT, what is suggested for shifting/fueling for the maximum fuel economy with this turbo set up. like what rpm should allow to build in 1st and 2nd gears with delayed shifts, primarily 1st and 2nd would be used for in-town driving and will help build boost/power and keep the charger up to help with smoke but would less fueling/power at bottom end be more efficient even if turbo isn't lighting and boost is minimal?
wow, i have a lot more questions but that will get us started!
now, I sit back - take over guys! :toast:
