"constants" question

have not touched my tuning equiptment for three months. using tunercat as my tuning software.
7747.
i found throgh installation of Innovate WB that my AE was too great. i think i was off the chart rich 8/1. i took away AE in both TPS and MAP and noticed direct results. took out 20% in both TPS and MAP each burn and checked with my WB. saw the result i desired. last log was November 2004 and was still rich on AE but drivability much better. issue this weekend is that i was burning a couple more chips for experimentation and discoverred i must have hit "minimum values" in their program.
ae %TPS 0 61
3.1 61
6.3 122

other TPS % values accept change(they are greater)

ae MAP kpa 0 61
20 61
40 183
60 305
80 427
these appear minimums as well. wont budge.

i have my BPW set accurrately for FP(12) and engine size(5.7L) and injector size(80).

am i seeing minimum values in the program?
is my injector size being large for a 5.7L not allowing me opportunity to adjust downward the AE any further??

There are more adjustments that can be made. As for the BPW term, need to ignore it when dealing with AE. It doesn't affect it. Change the BPW and the AE won't change.

'7747, there is the AE vs. Coolant table that can be used for further adjustments. This is an easy to use global change.

Can also change the TPS and MAP filter tables. Changing these tables will affect both the volume of AE and the duration of AE. Here the lower the value the greater thevolume and duration of AE.

Wow I didn't know those filter values would effect the AE like that, I just figured they were used for filtering for all the routines and should probably not be messed with. My engine seems to be much faster reacting to AE then a stock motor. I can get the initial lean spike tuned out of my AE tune, but I still go way rich for .5-1 second after the spike. I'll have to mess with that if the snow ever stops flying in the north east.

My situation varies based upon environmental temps. season is coming soon here in WI. temps are 40F in morn and my "choke" is/are good. i can generally drive car with about 2 minutes idle in driveway. i have no exhaust crossover heat(rpm heads). it takeas a while to get heat to manifold but better than it was with xram! if i add choke AND AE/coolant i may be too rich when temps warm up. my issue late last year was CL/ AE. the choke and coolant AE were not an issue IMO? maybe i am wrong on that. i asked TC to provide me with those filter values last year 11/2004 and i think they did but i have not yet added to TC program. on my to do list. i am puzzled as to why my AE has hit a minimum value in TC? think that is a programing issue with TC? i thought maybe theirr program balances BPW to values in program. i will accept BPW has no relationship to AE. i will send them (TC) an email.

Those arnt minimum values, theyre the smallest increment of AE that can be stored in the prom, which is decimal 1. TC incorrectly uses 61 as the conversion factor. I think the true conversion factor usecs of AE = raw AE as stored in the prom x 15.23 (15.26?).

i think you nailed it! i already too out the AE in new chip(s) one lesser amounts than the other and that may prove to be adequate removal amount.
