Here my mod :

Ecm : stg1 With Diablo tune Rev.17 (With stage-2 scale wg duty cycle by Biran)

stage 2 wg
Walbro 255 fuel pomp, Stock Regulator.
Stock s1 injector
94 oct gaz.

The winter in colder temperature, car was alway nice .
Idle afr 14.7
Crousing afr 14.7
wot afr 11.0 at 16-17 psi No knock
No hesitation.

Since is warmer outside :
Idle afr 14.7 to 15
Crousing afr : 15.5 and go lean to 16-17 for a couple a sec, and go back to normal. (Small hesitation sometime)
wot: 10.9 to 11.2 at 18 psi peak (No hesitation)

hesite sometime , when crousing normal , and giving a little gaz to accelerate back while in vac. In boost the problem seen to desapere and everything go back to normal. You can feel more easy those hesitation from a dead take off at a stop. The car backfire like hell when i downshift too

Fuel pressure sitting to 58 psi , which is normal . fuel regulator is normal and keep some fuel presure alway. No boost leak found.

What can it be? i dont have check engine. Can it be since my diablo was update then Brian left dsp, and rev.17 doesnt reconize my tune? all mecanic seen to be okay and, sg1 tune cousing too.

i dont know if diablo can take a look at my tune, to be sure it`s match with rev.17. I just bought my diablo from you 4-5 month ago at my name.

Btw i just join a log from normal crousing operation , maybe it gonna help u to find that what going on .

I hope to have some help.

Aside from the Wg adjustment there where a few other things that differed from the regular canned tunes, i implemented those changes in this attached file.
Give it a shot and let me know.

Haaaaaaaaaaa Nice, Maybe With the ton of job Biran had to do, he forgot to copy past someting. Btw what did u find diffirent from the canned tune, just by curiosity ?

Thanks a lot Johan. im gonna go road test this, and give you new.

there where some map parameters that where left stock in your file that really should be modified.

not able to load it .

Calib is my car serial number , when it should be 04510055ae

well im gonna send u my backup tune, this gonna help you.

The other one was , a tune brian did to turn rear o2 off, well i just left the rear o2 connected to avoid check engine, because both was doing the same.

For map ajustment, i can wait to test this, I was really rich on wot and , learn in crousing, Pretty sure your right on that

For some reason file i upload get corrupted, e-mail me and i will send you the file.
