There are a whole lot of things that can effect that. Where you are in the warmup enrich table could be causing some fuel trims. You could be in a different RPM or load cell int he map that is not properly tuned. Post your map again.

It works better in general Im not complaning

Im have change some cal in the last 2 days , and i hope to Zeroing the trigger today
(yesterday i spend the hole day dealing with the exhaust)

what do you think about the Automap Fuel log?
I want to install the Wideband propperlu today and use that, to fine tunnig the fuel map

Take a look of the cal attached

The cal file in the zip is an older firmware version. Did you backdate the ECU?

EB Turbo

rexset

Im using one older than the 1.19 and not the 1.19

By the way whats the difference between them?

rexset

i mean the 1.11

EB Turbo

The first cal you sent me was v1.19. Looking at it now it is a cal that someone had converted but didnt get running. You want to be on the latest version of the firmware. There are a lot of new tables in v1.19. Once you convert your current cal go to the setup tab (hammer and wrench crossing) and change the "Throttle analog input" to "TPS Voltage". Now go to setup > Sensors > Manifold Pressure sensor > Options. Set "MAP Analog Input" to "MAP Volts". These are bugs in the firmware conversion. V1.11 did not have the options and therefor they get lost when updating. Everything should work from there. Go through all of the tabs and familiarize yourself with some of the new tables. You will notice them.

Perfect

I will right now

rexset

ok here we go.
Let me know what do you think

You tell me.. How is the car? does it start better? idle? driveability? Did you want to switch to a full boost comp map? You can do it pretty easy with a calculator or an excel spread sheet. Do you understand what full boost comp means and how it makes tuning the AEM easier?

EB Turbo

rexset

Yep

It runs better by far
The only problem that i got it when i start it cold it runs for 5 sec and then stall , then i starter again with no problem, preatty strage thou.
I figure out last night the the wide band that i have dont show more than 3.9 volts at the output signal , but it keeps the linearity so its ok.
It run so much better with the firmware update , or probably cause i discover that the old map have a filter on the map sensor , so i took it of off.
Yep i understand the fuel compensation ,but i have never tunne like that
Can you explain me a little bit better the pros and cons and how safe is to do that thou?
Im booting my car now just to 9 psi , i allways start like that and then rise very slowly the boost and see how it react

This could just mean you need some more work on your starting tables.

Is this a non display uego controller? if so I would question the integrity of the controller. Because you do not have a gauge to compare to you are really relying on the 0-5v output and the calibration the ECU has to display lambda correctly.


Boost comp uses a mathematical formula that says if RPM and desired AFR are constant fuel required should double when manifold pressure doubles. So, 5000rpm, 14.7psi of boost takes 100 fuel increments to achieve 12:1AFR, this means at 5000rpm and 29.4psi of boost it should take 200 fuel increments to achieve 12:1AFR. The boost comp table is set up as a 1:1 linear scale. the boost comp table will automatically make changes for changing manifold pressure. The fuel map as you are using already does this. When switching to full boost comp all you will do is set the boost comp table to 1:1. You will make changes to your fuel map that reflect the changes to the boost comp map. This will keep your fuel map identical to what it is now. This will allow you to see more inconsistencies in the fuel map. Once you set one up you will see the difference.

AEM uses a MicroBit/Sec multiplier on the fuel table. This number is a multiplier that sets a scale on which the fuel table is allowed to adjust fuel. when having a large range of fuel increments in the fuel table say 1ms to 20ms you will need to have a large microbit/sec number. What this means is that every time you add or remove fuel from the table the increments are a larger jump. If you are able to give some fuel multiplication to other tables you are reducing the range in the main fuel table. This allows for a smaller MicroBit/Sec number and for finer adjustment in the fuel table. lets say on high MicroBit number one fuel increment will be a .1-.2AFR change and on lower MicroBit number one increment change will be .025-.05AFR change. This allows you to have finer control over your fuel table. Switching to full boost comp will allow you to set your MicroBit/Sec value as low as possible.

How do i change it?

And how do i calculate the boost com
Well to be fair it will be safer if i can variate the ratio
For ex i will need 10.5 af ratio at 10 psi but 10.2 at 15 psi , how can i do it with the comp
And i have the minimun boost at 8 psi cause of my wategate spring

rexset

Yes i have one of the first uego wide band gauge from AEM

I rewired it to the EXU ground and positive , but its the same
Max 3.9v , it seems like the gauge is slower than the ecu signal . Really strange , but i calibrate it as it should and i only une se gain factor at 0.98

All rows that you want to be the same afr will have the same value. If you want to have the 15psi row to be 3% richer you will just add 3% to that row.

Do you have a later version of your MAP? I will do the boost comp conversion and show you the differences as well as send you the map.

Im working on the map noe

Just hit another problem , it looks like my wategate is locked , onces o got to 5000 rpms the boost goes up without control . I have the acuator unplugged and a sring for 8psi , it goes upper than 13
I will try to fix that problem tomorrow

rexset

To small wastegate 40mm

I will need to go for twin wastegate setup

EB Turbo

iTrader: (1)

You could step up to a 60mm. Also a larger downpipe will help.

EB Turbo

rexset

I have a tein scroll manifold and another wastegate to spare
I got 3" downpipe till the tip of the exhaust
But how can it be posible?

EB Turbo

iTrader: (1)

Single gates on twin scroll manifolds don't usually work that well. Even a 40mm on a rotary in general doesn't usually work that well. 4'' downpipes are more desirable.

EB Turbo

rexset

I will install 2 40mm wastegates
Its just a pain in the a.. To take everithing off again

Ah Teck

Tuning probelm !

rexset

What do you mean?

EB Turbo

iTrader: (1)

Boost creep has nothing to do with tuning. If you run one boost refference to the bottom of the gate and you get creep it is purely a mechanical issue.

EB Turbo

rexset

Agree!!
I left the wasgate 100% open without a spring

rexset

Ok
just finish installing my gt3586HTA t4 1.06
is quite rich all the range till 7300rpm that goes to a/f 11.1 and is seems kind of choque
probably cause im just working at 7psi

some bugs at 4500 at 50% throttle

dirvelity under 4500 rpms is excelent even when i need to clean the map cause it need more advance ing and be more lean.


here is my map.
