I've seen steck say fuel on cranking isn't the answer. I'll bump the first column up. It smells fuely once it fires so I'd say it has enough
they didnt, used deka 100 data from a&a. fired first try so i know its good enough. Can compensate in the tune for other little differences.
How long is the exhaust? if its a short dumped pipe decel and idle afr's might not be very accurate. I dont have a permanent wideband on my truck but on decel my trims all go rich -18%, did the same...

Looking for some help on startup airflow. stock 5.3 with lsa and ls7 maf. stock cam. 100@ holley injectors. truck started ok on gas, when i switched to flex it takes 2 cranks to fire under...
Glad I saw this, i tried the fa mult table to add a bunch of fuel for the cold starts. going to change it back and add spark
Procrastinated on this and finally went through the steps and this write up made it easy! Took me about an hour only
Wtf this is so much easier
Cool, I have all the injector data in already. Hopefully this helps my transient issues. I'm going to run out of maf and spark tables but that's just an excuse for a ls7 maf. Thanks guys I'll post...
Will the x2 stoich half ivt ifr method work on the early e38s?
The stock tune and the scaled tune are at the same spots in the spark tables and maf scale. If I unscale it I run out of everything
If I do that I'm going to run out of spark table. Half of the reason for scaling this way was maf resolution and not maxing out the spark table. This is a first gen e38 so the tables are much smaller
I don't have it scaled that way

I recently did a 2bar e38 and it did the same. i failed the maf, wacked 20% in the ve and it would idle like dog sh!t and drive like crap. I ended up put the maf cal back in and been running great...
