Bought a car with a Wolf 3D, what's needed to upgrade the map sensor?
 
Bought a FD with a Wolf 3D, I was told it only had a 22 or so psi map sensor installed. He said it's actually built into the ECU, is this correct? If so, what's needed to upgrade it to say a 30 psi sensor? How to and price?

internal dont get updated / sucks eh?

you can solder in a new 4bar or 5bar but i dont know what affects that'll have on the firmware.
this was something i looked into and Wolf AUS being a jerks they are attempted to sell me a v5.. jerks :-)

The Map Sensor can't be upgraded? What the.......... So yeah; that puts a big kink in my plans.

The internal cannot, you can run an external however of whatever range you want aslong as its 0-5v

Viking War Hammer 03-23-10 06:19 PM

Is there a certain way to wire that up? Would I need to bypass the internal sensor?

CrackHeadMel 03-23-10 06:33 PM

Pin 24 is the signal wire for external map sensor

As for switching it over in the software, i know you can i just dont remember right now. I am however sure though because i have a 4bar Motorola map sensor sitting next to my wolf3d v4 that at the time i bought it, i was sure i could use it.


Wiring / install info for wolf3d v4

Pinout's are on page 62



You sure are not wasting anytime modifying the new FD.. :D

PC software manual

It does mention in the setup where you choose load sensing type, you can choose internal or external map sensors

On the hand held controller i belive you hold the top two buttons for 3 seconds and it brings up the setup menu, i may be wrong though, cars been apart for a few years.

well uhm, you physically can swap it for a newer one but the firmware not knowing the new range would set ya back.

MAYBE we could start a firmware hack session again. I dont have a wolf 3d+ and I surely wouldn't buy another but I would be willing to help if a spare one comes along.

CrackHeadMel 03-24-10 08:24 PM

Just run an external and scale the map however you want? Any 0-5v map sensor will work, far far far easier than modifying the internal

and as far as the internal, if its a 0-5v you could just swap it for whatever you want again aswell, only thing that would be wrong was the readout in the software or hand held controller.

Right! And thats why we shoulda started modifying the firmware from the start.
Wolf sucked at this and customer support.

Which version Wolf 3D is it? I think v3.0 was limited to 22psi with he internal sensor. The v4.0 added the external MAP for boost above 23psi.

Wolf uses a percentage value for load in the software tables. Therefore, the pressure range of the MAP sensor doesn't matter for tuning the tables, nor does it matter if you select TPS or MAF for load. The only difference is that the "psi" readout would be inaccurate with an external MAP sensor. The Wolf software has allowed the user to rescale the load with a Windows interface since back when most of their competition was still using the old inflexible DOS tables and confusing macros.

Wolf always sucked at customer support, and I would imagine that this has not changed recently.

It seems when Joe User tries to get some help he cant, I hear this with almost every ECU out there.

I dont do my own tuning and have never attempted to get any support myself, but I do know that I have seen my tuner get on the phone and call someone in Australia on a few occasions, and he always got someone on the phone and got answers, Im assuming he is calling someone's personal cell phone.

So I guess as usual its who you know.

nyt 04-03-10 11:05 PM

they helped out when i needed my ecu reflashed. they were slow about it, but you can still call them and they'll answer questions.
