well for the last year I have ran a holley avenger hp ecu on my procharged 383 stealth ram.i am running auto tune but wanted to use meth/n20 and boost control features of ecu but ecu will not let you with auto tune.I have been running this with a 1 bar map sensor and I know a 2 bar would be much more suited for this. so I put on a 2bar hooked lap top to ecu and then installed base cal for fuel and spark tables.after this it took me over an hour to start and still cant get it to idle less than 1800 rpm.wideband afr is all over the place and goes from 20 to1 to 10 to 1.so I thought something was wrong so I swaped back to auto tune and 1bar sensor and it runs great 800 rpm idle 13.1 afr fairly smooth idle.so I have determined that I suck at tuning and only know enough to get myself in trouble.just looking for any suggestions or even someone that is in richmond va area to give me a hand. called several dyno shops in my area and they wont touch a holley hp just gm,ford,chrysler,import ecu's.

 

Have you tried calling Holleys' tech line?

 

Have not called Holley yet but did a datalog with autotune and compared to base map of 2 bar and 2 bar is about 3.5 pph fuel and autotune is 9.25pph so i have a feeling it is way to lean.this was just idle at about 70kpa

 

Holley has a great forum also. Danny seems to reply to almost every thread on there and is a wealth of information.

 

Thanks lurbie I probably should have looked there first.danny has gave me good insite from previous post.will make many changes to current 2 bar map and give it a go this weekend

 

If you want, pm me and I can give you my email to send the global folders to. I know you NEED to use the 2 bar with boost.

 

Pm me a copy of the file and let me look at it for you and I can probably easily get you where you need to be. I am a dealer and installation center for holley here in Cincy. If you can't post the global send it to my email. Tracy@cincyspeed.com

 

Did you change to a 2 bar map sensor in your system settings??
