that fuel seems really high. don't worry about how much fuel you have to take out. you have 1000cc injectors which is a lot larger than that base map is made for so you're going to have to lose a lot of that fuel.

My fuel cells down in the idle with my hks1000's are down in the low 20's.

 

and furhter looking at it, you have just as much fuel being poured in at -14mmhg (which is where my car is cruising) as you do at 7psi of boost in the 3000 rpm range. do you honestly think your car needs the same fuel in -14 vacuum as 7psi of boost at hte same rpm? HELL NO!

 

That is the base map BEFORE I did anything to it.

Here is it after:

 

so you dropped about 12% fuel in the decel area. That's still not much. remember, You need less than half the fuel in vac that you'll need in 0psi. You're still way too rich.

my decel cells are in the teens. each motor is going to be slightly different and i understand that but with the same injectors there isn't going to be 1 car in the teens and another in the 90's. That's a HUGE difference.

 

Can you please post a pic of your fuel table? thanks.

 

So. you mean something like this:




I also will change the fuel injector dead-time to the higher value. see it down:


10v 1.31

11v 1.14

12v 1.04

13v 0.97

14v 0.89

15V 0.79
.

 

my negatives are in mmHG so half my vac numbers to get what psi (-10mmhg= -5psi)

it goes further left but i couldn't get it all on the pic. That's a quick show for you.

 

I see.. Thanks alot for the help.

 

wow I have no clue on what all those numbers and colors mean..
is it possible to tune your own car if I learnt(learned)?

 

you need to get learnt at a school, best way or if you have a beater you can f with, learnt it that way.

 

I tune my own car. I just take it to Hal to do the final touches and make it perfect as well as safe timing on wot pulls. Basically all the things I can't do without a dyno and the extra fine tuning from his experience.

 

lol haters gonna hate haha

 

This one I just tried, it idle/drive nice 14-15afr. I only tried it to around 3000rpm for now.



I will try to tune the rest of the vacuum cells when I have someone else driving for me.

Thanks binder for the help.

 

no problem. those numbers look a lot better.

i'm still dialing mine in. putting my external sensor in this afternoon and i'm going to go do some more vac tuning.

 

Will it be better to use the copythrough in the vacuum cells in the fuel table?

BTW, I have the GTM reflash.

 

^^ I just remembered that I have the 1000cc's injectors and that's a no no with the stock ECU.

 

low or high impedance?

 

Low.

 

those numbers have nothing to do with injector size, that is volumetric efficiency. you could have 390cc injectors or 2000cc injectors; when tuning on the same engine with VE the % will be the same regardless of injector size given that injector flow is set up correctly.

i was under the impression the stock ecu couldnt run low impedance injectors... someone correct me if im wrong.
