installed table switching hardware and now lean off throttle

Postby turbothis » Sat Sep 09, 2017 3:23 pm

i got the table switching working fine it seems by the way it runs and the dashboard icon lights up on msdroid saying it is switched
now i have a strange very lean spot when off throttle or just at the lightest cruise
i will get a picture of the wiring soon
trying to add my msdroid tune for review

If I'm understanding, you;re saying you have a lean spot when table-switched? For the fact that both VE1 and VE3 are largely the same, compare from 500-2200 rpm, up to 50kpa. VE3 is a bit leaner there than VE1.

since i started the table switch i have only ran ve1 which is my E85 tune
it was nasty great before table switching
power side is still solid but has a crazy lean cruise and slightly under throtttle setting
i will get a log of this today and after that unwire it to see if it goes away.....
thanks for the reply

ok here is a log of the lean ness
i turned off the fuel and spark table switching and the lean is the same
next i will unsolder the leads inside the box to see if that is the issue

for reference V1 is E85 and VE3 is super unleaded

maybe my wiring is bad?

5v from led17 resistor (black wire)

Image

diodes are oriented correctly i think (both black wires are the switch)

Image

0v from db9 pin 9 i believe

man, i removed the table switch hardware and it remains a lean phantom

i swear it was not like this before i wired in the parts

i guess i will load the original 1 table E85 tune ( i swear was good) and see about tuning out the lean phantom if it is in there too?

glad you mentioned that!
i did some initial autotuning with tunerstudios on my laptop (WIN7)
then i watch the gauges of things on my tablet (android)

somewhere in there the load tune or update controller or one of the super fancy options i choice poorly or something
now i can solder up the table switch stuff again and just continue the tuning

sorry for the waste and thanks for the help
