hello i have a 03 suburban ecm in a 85 el camino when i shift to reverse from park the RPM drops to 300-400 rpm sometimes it will die sometimes it wont.

im going to verify today around my lunch , i changed the pump last year (June 2021) so it should be good its a walbro 255

so its my VE going to stay in the higher 140's at Wot ? no matter what i do it seems that only wot seems it just keeps getting leaner or no change at all

mines are not dead accurate i keep seeing about .4-1.2 afr change when my values are entered without the spaces and parentheses

Thank You, I will give it a try in the am to see if it helps lower my VE # in the higher Rpm

I think i messed up a couple Spaces and parentheses like you said in a earlier post because hondaeater's math made everything come together accurate gauge and scanner better than i had it

hello can some one tell me if i have the correct injector data for stock ls3 injector in a 99 camaro ecu

#12576341.

yes i seen on my gauge the afr would go up in the 20's when i would get on the gas pass 40%



so do you want me just to use these math equations instead of the ones i made ?

i didnt have a chance to log until after work but here is a quick scan

ok i will be on lunch in the next 45 mins so i will go for a drive and log

ill double check my all the settings i have while i work

lol i tried a log with both set up in my scanner and my afr error could be right car is showing its running lean by about 18% (i think thats what the 18% means) but the lambda is reading 1 and lambda...

well i decided i might as well learn for both ways (lambda vs AFR) i set the lambda charts up the same way as i did the AFR chart's is this correct ? 130682130683130684130685

not yet im going to try the math for lambda today last night i was stumped with it not working 100% correctly

so basically i would the same formula but just the math for lambda instead right ?...

so i looked it up for my car and it goes

14 RED/BLK A/C Refrigerant Pressure signal (A/C)
80 BLK Low Reference (A/C)
45 GRY 5 Volt Reference (A/C

so i should hook my ground to the low ref...

now after i went to the muffler shop and had them install a permanent o2 bung instead of just the one on my longtubes the sensor and the scanner are very close maybe my cpu is just polling slower...

so i connected it to the AC pressure switch red wire and grounded to the battery im getting closer now WB is reading 18.3 key on engine off and now scanner is reading about 17.23 130650

this is...

Still 0v


if i do it the way from page 10 it shows like 8.5 in the chart vs time ......WB EGR Lambda channel vs WB EGR AFR channel i didnt see this in the channel list

and either way i put it...

i referenced this video do to him doing the same method as me and still no luck
i even grounded the brown wire to a straight to the battery still no luck

so i tried again with how i wrote the formula out and 130645
this is what i get now

i have the EGR sensor pid in my channels

from one of the threads here on hptuners

when i try that formula it gives me -50 across the board in the scanner im going to try again


like this right
(2.3750*[2811.10])+7.3125

Hello 99 Camaro
I installed a Aem 30-0300 using the EGR port (blue55 and red41)
The gauge I assume is reading correctly but for the life of me cannot get the scanner to read the same or even...

im not sure why i am not able to see the channels from the xml file you posted. Yes only the cold start is the issue, especially when it was winter time it would idle really low and eventually bring...
