Just got back from shop. Finally proof of improvement C02xL 1.41/5.4 HC ppmxL 331/537 NO ppmxL 1651/7380 pass! with only 2mi warm up to shop still passed got my sticker . I'm still planing on...

ok verified that 47psi was accurate and that the pump could not get it to 62 until the return line was clamped so figured had such great luck with the last pump just change it.
so after weeks of...

log from test around block after i put new plenum gasket not any different from this morning . high blm. fuel psi i gave u is not accurate i have a oil pressure gauge and sending unit connected to...

cool out today log seems leaner i think the reused plenum gasket is leaking

Like bad lean? Bad vacuum switch on transfer case might be bleeding vacuum and causing lean i removed from vacuum circuit and will pull another log . fuel bleeds off real quick after shutoff will...

So After A Very long wait i have a remaned cpi! I have had a vast improvement in drivability since intake and small increase in mpg . After cpi was installed idle improved, exhaust fumes smell much...

yes i there was a new pump, filter,nut kit, cpi installed . i thought the new ecm seemed to be be a little less jittery spark and fuel trims weren't jumping around as much . but decided to do a...

i think it was bosch. i will eventually have more of these so ill hang on to the ecm and in time get the burner and all that . TH TB is before i put new o2 in idk if you'll see any difference i...

i have usb aldl redevil datalogger and tunerpro . co2 42.95 (limit 5.4) HC ppm 1097 (limit 537) NO ppm 494 (limit 7380)

i read that same thread on battery voltage...too.. just didn't know how they switched it. do i go to acquisition and edit definition , value , knock ? idk how to switch it . cats only 2years old i...

back to square one now i have a spare ecm to play with. so were to go next ? first start log and putt around block with new ecm started really rough and go better but knock is still there on start up...

well i just had them ship it , so it wont need a flash right? just pop it in and do a relearn of some sort? Brian i sincerely thank you for devoting your personal time to help me out and look at...

all have continuity and no grounded circuits . this has same ecu pcm # as mine except i think the serial number would this be plug n play ? option ...

it seems to run ok just wont pass emissions slightly rough idle , occasional missing on startup , compared to my bros it lacks power but not extreme . i have tested with light in base timing stays...

bbc for ya

From drive to work

yeah probably didn't reset pcm before log they kept setting because i was disconnecting it to look for interference , im getting a fresh log today on the $E6 with rest pcm by disconnecting...

so if the knock sensors lets say eliminated what else controles spark retard? i have swapped icm with a good one no difference

switched files i think you r right when i first got my files i didn't have my ecm and ecu #. but no difference in retard and it switched some vales around on dash board seems the same

on start up it jumps to 100 or so knock counts i think that's normal my bros logs seem to do the same , after that no counts so i don't think i have wiring issue , i checked wire insulation no...

i think the valves could use adjustment little noisy at covers i'll pull both sensors connectors and check, never thought of interference would that be because of crap plug wires? and what does the...

sorry yes i have two knock sensors and i just double checked to see if it was grounded and its not i tested from ecu connector to battery

wow dr that's the fastest response ever for me thx. fixed the text color , yes i believe it was blue i tested between ecu connector and both sensors for continuity and tested fine . i guess just...

94 s10 blazer W vin 4wd 4dr 4.3 ecm # 16168625 16179571
i have aldl usb and tuner pro 5.0 to pull data .
data stream shows full retard on start up constantly starts at 24ish and works it way up...
