ok it runs rich as hell on the cold start and running. what am i adjusting? i know a few people have had a problem with this. timing maps were way different than my v8 cal i had before. i put them to where the v8 was.

pump eff table doesnt seem to effect cold map fuel hardly. so dont tell me that.

Copy the entire files, adjust the injectors to 10% or 20% bigger, than compare the "starting fuel" values to your original files and adjust your original files.

Just found this one while working on the T3 code. The table "AESLOP_DeltaMAPEnrichment_FromTemp2" needs to be inversely scaled for MAP. Right now, MP Tuner can't do that automatically. So, you'll have to do it manually. If you went to a 3-bar MAP, scale it by 150% in MP Tuner.

On the T3 anyway, it resulted in a rich idle.

Ok that helped a ton!! Went from 10's to 13's. I just matched an old v8 table i still had and it fixed it. Now I have to find a way to get my popcorn sound back on decel. It's not running rich or anything. It just doesn't pop like the old days on decel. Any input on that? Like I can't explain it. It just sounds like it's not getting fire on decel lol. Not like the normal pop pop pop.

On the LM, I have no idea. Probably the idle fuel table (FuelNoThrottle) in vacuum. The LM doesn't have the decel fuel cut that the SBEC cals have.

The older version of turbonator had fuel no throttle table. Now it doesn't. I see full throttle and part.

I think it may be timing related. It's not running rich on decel. It reads 18+ on decel. I see a lean out factor off throttle table. I tried messing with that but doesnt seem to effect it much. It was jacked wayyyy up under 1000rpm. I lowered it to where it was in v8

So you mean pull it down 150%?

It's called fuel idle or something like that. I commonized the names with the SMEC and SBEC versions. But, it's there somewhere.

No, scale it UP. 1.5x or 150% in MP Tuner. That's for a 3-bar MAP. For a 4-bar MAP, double it, etc. It needs to be scaled with both MAP and injectors. Its a new discovery I found while working on the T3 cals. MP Tuner doesn't do that kind of scaling right now. Morris is looking into it.

Here you go. Ok green line is where it was without me touching it. Blue is where I had it today which is a copy of the v8 tune. The light blue is where I just moved it. Do I need to move it up more?
roachjuice

I was lying. It didnt lean it. It made it richer. I had my fourplay set on the wrong tune this morning. So this afternoon I went to go home and I set it on the correct one and it was richer lol. Sorry about that.

That didn't seem to help on decel fuel. I turned the fuel down below -11psi. Add fuel maybe?

Rob, I never scaled that table on my cal w/ I set it for 3-bar, and mine starts fine in all weather and temps. I have a 2.2, if it makes any difference. Roach has a 2.5. You think it would be any better if I did scale it?

Edit: I don't even see that table in my cal? Using Template A171, T-LM V12.5 on MPTuner V1 (I don't like the new MpTune V2 interface :p).

Look for "MAPIDL_FuelBaselineFromMap" - it's the same table, I just changed the name to match the SMEC and SBEC cals for comparison purposes. Same function, too; it's the idle fuel table.

I just looked - it's there in v12.5...

Basically, it's a transient fuel calculation. It's a small PW generally. But, at idle, it does come into play when the AIS changes position (and MAP changes). It works anytime there is a MAP change, idle or otherwise.

What I don't really understand is, how it leans the idle out. It ADDS PW by scaling it up. But, it has the effect of leaning it out. There must be some kind of overflow issue that I'm not seeing.

ok. yea i did the pump eff table for that and it made it lean by one click.

Didn't touch his timing or PE table, its bone stock, so not risking it.

Why not? I thought I was taking out too much timing and people didn't go too far from the factory timing?

I left the timing tables stock, no ping at 10 psi.

Fueling was weird, I started off with a rich warm idle, leaned it out, so then the friggin ox wouldn't toggle, kept playing and gave up, then it was rich off idle, so played with that and it cleaned up, but its a weird PE table around 20-10 inchs of vac. It passed our aircare so that's all that counts and its got lots of power.

I would imagine no ping at 10. Because it's a stock timing map.

What turbo? Why the large injectors? What octane gas? Alky? Porting? Stock cam? What intake? T/B size? Header?
