I am 466 above sea level

 

I'm at 40ft elevation and with Walbro 255 and 550 injectors have it set to 63. AFRs are to spec. IDC is good too.

 

thanks Lenin. IDC (I dont care). lol I dont wanna blow my engine

 

IDC is injector duty cycle. Lenin, how do you log IDC?

 

jesse james lol. thanks

 

your welcome austin bar rylee

 

I have mine set at 66 with stock injectors and AFRs are fine.

 

Your list of mods is awesome and you're flying pretty good now I'm sure; and I'm hoping you have an AFR monitor/gauge (at a minimum) to really see what's going on with your engine, since we're all just a little different. Plus or Minus so to speak.

 

thanks. i do have an aem afr gauge on pillar

 

I'm getting ready to install my new sl65 fuel pump this weekend and will soon be upgrading from 65mm to the 62mm Karmen pulley. I'll be purchasing the AEM regulator kit and filter from Rob, so the info. on this thread will be a good starting point as to where to start with the pressure adjustment.

 

theres some controversy against the 62. i have not had any problems with it but only have 5k on it.

 

Yes, I've been following that too. Did you get yours from Rudy's group buy? If you don't have it already, good piece of mind is LM21's pulley scatter shield.

 

i got mine from maker khang vo. it was a leftover. i dont know if its ruby version or not

 

Injector 1 wire (one of the ECU connectors) into Innovate SSI4 into Dashdaq.

 

Here we go again.......and he loves being called Ruby !

 

Better than being called Sue.
Sue.

 

Whoops! I didn't mean to open up old news, sorry bout that.

 

calm down typo. RUDY

 

i was just trying to find out where to set the gauge for proper afr
