Haven't been n here in awhile,spent hours looking at posts last night.
Could I get someone to look at theses a/f tables and give me any help what would be best or any changes to make.

Do I need to do any thing with timing.?
Please and Thank u

 

Depends on what your objective is, and if there's a problem you're trying to fix. Overall, those mixtures look fine to me for combined fuel economy and performance, but could probably be fattened up a bit on the 40% and 60% throttle positions in the 2750 - 3500 range. I'd be far more concerned about timing than mixture though.

Is this the stock map?

 

Thanks for your reply.
Started with a canned map for a 110 with Andrews 54 g cams
a/f table is what i came up with from hours of reading
i talked to zippers they wont give ant Intel on timing unless i buy a 800 dollar tunner from them.
Would you have an idea what would be save to start with..
I usually run 100% gas would rather have performance over fuel economy..
Seems like it wanting to load up after hot sitting at light on off idle only.
Power commander told me to hook up stock sensors too.
really appreciate any help.

 

Timing is a really tough thing to get right, unless you have a lot of money for dyno time and a patient, competent tuner to do the job, or you're lucky enough to find someone who's had this work done on a very similar build and is willing to share their map with you.

Barring that, it's a matter of trial and errror. Go for a ride listening closely for sounds of detonation as you put your engine through its paces, advance the timing until you start to get knock under load, then adjust back 2 or 3 degrees from the setting where you start to hear knock. For those sections where you don't experience knock (cruise and idle for example), it's a matter of playing with the timing to get it running best, accelerating out of the adjustment range smoothly, etc. This is a very tedious process, I assure you, but there really is no other way that I know of around it, except to live with what you have (assuming you're not running to hot or experiencing knock - if you are, you really need to do something about it.)

 

Also, the most consistent advice I've gotten regarding mixture is the following:

Target AFRs:
Idle: 13.8-14.2
Cruise: 13.8 - 14
WOT: 12.5 - 12.7

 

You got me thinking about this topic, and since I'm in the middle of fine-tuning my engine (with a PC III USB) I thought I'd put together an optimization table of my own.

I'd really appreciate feedback on this from the many here who are more knowledgable on this topic than I am.

My thinking was, since my system is open loop:
1. Be safe with decel ranges, especially those that in some scenarios might not be during decel
2. Optimize the table to be leaning toward economy, but not at the expense of performance when I reach deep for torque or power.

Here's what I came up with. Tell me where I could do better!

 

Ironhauler: Unlike you, I have an open loop system with no manifold pressure feedback to the ECM, which makes the result of tuning much less precise across the spectrum of engine state conditions.

Here's the target a/f table I've settled on:

 

have you done head work ,,,whats the compression ratio ...or have you just installed the cams in a stock motor ???

if so ...what cam was taken out ..the 255's ...??? if so when installing the 575's on a stock motor ...you have dropped the compression down from a already low 9.3

 

Yes 255 taken out of stock cvo 110 motor.

we believe you should start with a zero map and retest (see how it runs ) ..with the lower compression , you will have to advance the timing at least a couple degrees to start with ...(on both front and rear timing tables )
you haven't shown the timing or fuel tables ...set the AFR for both front and rear at a 13.5 across the board for a starting point ( you need to remember that you are trying to run on the stock map and only adding and subtracting from a stock ECM..with no feedback )
add 2 degrees timing for both cylinders ..(this is the most important table you must get right ) (retest at idle and make changes up and down to see how it reacts )
on the fuel tables (remember stock maps run near 14.6 ...so with 0 this will be lean...try adding 2-3% ) but remember during warm up the ecm adds fuel til temp is up to about 170-200 )
this will take alot of small changes and patience...
good luck ...
