How do I get 12P to go into closed loop mode

take note of injector duty cycle too ... got any logs ?

This is the last log I have taken

From just a quick look (will check it out better later) it looks like you in single fire mode which wont be helping.

Have a look at what you have set for..
"Run A/F Param - Minimum BPW for sync double fire fuel delivery (Min Value)" - set it to 0
"Run A/F Param - Minimum BPW for sync double fire fuel delivery (Upper Value)" - set it to 0
"Map A: set=Single fire option, clear=Double fire option" - Clear the flag

jesus its lean on boost 18:1

its also not displaying a 4 cylinder memcal in the aldl

Thanks I will have a look tomorrow. If I set the values to double fire will it affect my VE values or will they be the same? It should show 4cyl but I will investigate. I think the 18:1 is not correct due to the missfire and obvious lean mixture reading.

I had a look and have changed to double fire but can't find how I set to 4cyl memcal? I have it set to 4cyl so do I have to change anything else?

Its the actual physical memcal that is currently not 4 cyl - its using TBI mode currently so will run very lean if you just change that to 4 cyl. In saying that though, you have fluked it as having it set to TBI mode and single fire it will inject the same amount of fuel as 4 cyl in double fire.

If your running a modded memcal then these are how to select the different types .. http://pcmhacking.net/forums/viewtopic. ... t=10#p6850

Thanks for bringing that to my attention. I went through my eprom collection and found a 1.8 multipoint Camira and set it up with the 27sf512 and knock board and started again. I can now see 4cyl memcal and found I had to reset the injector flow rate and richen the VE tables to get it back to near the same wideband figures it had before but all going great now. I'll have to take it for a drive a make a new log.

I have looked at the memcal resistor diagram and if I cut the legs and fit the two resistors as shown in the diagram will it them work as a 4cyl memcal? and if so will limp mode work? The reason I ask is I have 4 other tbi memcals I would like to convert. Funny that I picked 2 mecals out of the bag without knowing this and they are both tbi.
