good morning (09/21/11) they call me jimk. i am new to the beta test (sequencer world) i have been into ms1 and ms2 for 8 or 9 years now. i have completed the physical install of the sequencer on my truck. my engine == 440 dodge = +.040, home made port inj intake, 42# hi z inj, 900 cfm holley tb, comp cams hyd roller cam (.538 lift and lumpy), comp roller rockers, 10/1 cr srp forged pistons, extensive head work, rotating assy balanced, dist reworked for cam sensor, 36-1 crank wheel, gm ls2 truck coil packs, wbO2 (lc-1). i have posted the install prep info on the ramcharger.com website. you can take a look at this info there by going to ramcharger.com and look under projects section and then sequencer install. i will try to post a direct link also.
the engine runs and starts well. there are a couple of things i am not comfortable with. #1. sequencer seems to stay in warmup enrichment mode all the time.
#2. i don't see an indication on the acceleration led that i am getting any acc enrichment. i only see a slight bog when the engine is cold. works great when warmed up.
#3. wbO2 - afr seem rich, may be related to warmup? otherwise the truck runs great.
i am posting my msq and a short data log. as said before i am new to tuner studio and data-logging. if some of you gurus could take a look at them and offer recommendations it would be much appreciated. thks jimk

Re: new sequencer installation/testing
Jim,
Just from your datalog, you can see the coolant temp is actually going from 115 to 105 deg. Something is obviously wrong there, either wiring or the temperature sensor was not calibrated.
Your accel problem is probably related to your tpsdot threshold. If you look at the tpsdot column, which is what triggers accel enrichment, you will see it never goes above 90, but your threshold in your msq is set at 200. From your data I would set it at about 50 and work down in steps of 10 if this isn't enough.
I think those 2 will take care of your afr readings. The main thing is you are getting synch and the engine is running, it looks like just a matter of tuning now.

Re: new sequencer installation/testing
good day ladys & gents. jimk here.
al thanks for the guidance. i set the acc threshold to 50 and it did the trick. the warm up problem turned out to be that i had miss plugged the connectors on the clt and iat. they are almost next to each other on my engine. re plugged them and all is well with my warm-up problem. i suppose that is why the data log showed the temp going down as i drove the truck. (getting cooler air thru the intake). as far as the afr problem i was having, i checked the wiring again and read the lc-1 install info again. i had wired the yellow wire from the lc-1 to the sequencer which simulates a narrow band signal. i should have used the brown wire instead. i switched them and now get a normal afr reading. truck runs great. i think i will use some ts auto-tuning and see how it goes. right now i can't detect or see anything i want to change. thanks again. ==jimk==

Re: new sequencer installation/testing
10/04/11 - followup - with colder weather i have had to increase the warm-up table a bit for smooth warm-up. other than that sequencer has been great. on lingering problems to report. jimk
Re: new sequencer installation/testing
Appreciate the comments - no news is actually good news. For those of us who don't have environmental rooms where the engine can be tested from -40 to 120 deg all day, its necessary to take at least 6 months to tune through the entire temp range.
