TunerPro User Forum

Hi Everyone,

So i've recently been playing around with an automatic E36 - catless and a few other minor mods.

I've gotten the XDF file from tunerpro for the 413 ecu and a few SST27SF512 chips to play around with but no matter what i am unable to get pops and bangs or burbles on the tune.

Everything else seems to function just fine (rev limited, speed limiter etc etc)

Is it the wrong XDF or do i need to go more in depth? i've been told not many people are able to acheive pops and bangs on OBD1 413 ECU's.

Any help towards this would be appreciated.. below is the stock BIN file for my vehicle.

Thanks!

retard the igntion in low load and add fuel in the same area (part throtle body) ... and touch the pedal a little bit , it should pop

Tried that, barely works....

0xDC73 - Coolant temperature dependent overrun fuel cut RPM. Fuel cut is active above those RPM values (x*40), when throttle is in "idle" position. Not very economy, but... By editing this table you can modify or disable overrun fuel cut.

Do you have emulator?

anyone know the decceleration maps on thoose ecu's ?? or 402 one ?
i already have the decelaration fuel map ( fuel overrun) for 402 i need the ignition one tobe able to retard it in deceleration

I'll go ahead and try this, i currently got the car to pop and bang easily in my given rev range, Sounds like a popcorn machine haha.. but still no flames, i'll try with your addition and see how it goes.

how did you manage to it ??
which way did you did it ??

an update to this thread... 413 easily now has pop and bangs or crackles... both different maps. Auto or Manual transmission, both are possible. Check out my tuning page on facebook for videos and stuff. fb.com/dirtysixtuning
