Alfa 2.0 V6 turbo

[lost]

free at last, sunday, tryed to tune it. to get to tareget lambda, idle rises and lowers,  the problem is that when i push throttle faster lambda jumps tp 1.2 or so and i get miss fire. also when i slowley push pedal up to 3000 rpm turbo starts to kick in getting close to zero and into boost) and then it stops. with the strange sound :) i dont know how to explain.

Can anyone who has magalog viewer check it out and maybe sort out tables / acl. enrichment? I'm scared that i dont melt the engine. colant gets high really fast.

edit : ego correction was turned off.


using 1. 1 47 v2

Your ovefuelling like mad to the point of missfire.,

You need to map this to make it work right,
can you do mapping yourself? Do you understand the variables and what to do?
If not then seeking the assistance of a professional is a good move or get some books on the subject and read up.

Tune the VE table first then worry about the throttle accelaration enrichment.

decided to calibrate wbo2 and mount. i never finished calibration steps that included using 100 ohm resistors.

so i have quick question , when connecting 100ohm resistors between pin's do need to have wbo2 plugged or unplugged to vems?

disconect WBO2.
Did you turn on wbo2(Manmde02) and wait for 1-2min?

2mwfire: didnt tryed it with resistors. but with onley wbo2 connected it heats...

got -0.17v on pump zero pw calibration is this OK ?

[lost]

got 4.01v between gnd and  pump -( pin5)

and 0.45v between pump- (pin5) and nerst (pin1)

that seems to be acceptable?!

o2 reading is 20.4 to 20.8 with wbo2 in  clean exhaust (didn't started engine today)

can anyone confirm this valueas are ok?

anyoone? ;D

Go to "Calibrating the WB02 controller circuit" its all there :)

didn't touched vems for a month  ;D

alfa is back on motronic, dont want to play with boost without EGT probe.

First need to find a good place to mount it.

Here ar cyl 4-5-6 with colored dots, so i need some advice where to drill.

how deep tip of the probe need to be in exhaust?

thx.

Personally I would got further down the manifold to where the three pipes join.

i can do it that way. at that point how high egt can be (safety limit)? 850 C?

is it possible to slightly bent thicker egt probe from vems shop?

around 45 degrees at middle?

[gunni]

I don´t think it will handle 45° , I have managed about 25-30° in the middle to clear a downpipe.

Do i need to solder something on v3.5 board to use tacho safe ?

Is is possible to use ign7 with igbt installed or just use p259?
