Tuners Rejoice! Free Tuning For M4.4!


Recommended Posts

Hello guuuuuuuuuuuuys ! I'm baaaaaaaaaaaack ! :)

Sorry for the long absence, for the 4 years me and a friend of mine had put together up a small VOLVO repair shop here in Romania, which in time grew bigger and bigger (we now have 8 lifts).
Unfortunately I had to leave from the business and from the tuning scene as a little girl appeared in our lives :)

But she's 2 years now and I'm starting to have more free time, and I'm getting back to my old love, my T5 S70.
3 years ago a tree fell over the top and bent it like hell. She's been parked in the same place and never moved since :(

It's in a repair shop now for making her straight again, and I'll be off installing the new GT3071 that's been waiting for 4 years on the shelf.

Hope you're all well and staying safe from the new COVID. Glad to be back !

Welcome back Midnight Caller! 

I wish you the best of luck with the Volvo.  GT3071 will be awesome! I run a GTX3076 and is wonderful!

Hey guys . I just got a 1998 C70 m4.4 turbo and im very happy with the car. Yesterday i replaced the turbo and the exhaust manifold from S60R and i got the Turnerpro software running + i did the flashing succesfully. Guys i have 2 questions about the MAP sensor and the Wideband that are not explained in more understandable language, sorry im not so smart when it comes to programming language and terms sorry...  So can somebody explain simply how to and  is it possible to connect this MAP sensor  i think its 3 bar (MPXH6300AC6T1- i had it from my previuous project Honda Civic ) in the ECU housing  and should i connect it to the Secondary O2 or the TANk pressure inputs ???  Btw i dont know if i have tank pressure sensor. Where is it located ? 
 I have an AEM wideband model AEM Electronics X-Series Wideband UEGO Air/Fuel Sensor Controller Gauges 30-0300 im puzzled on where to connect this one since i read somewhere in the topic that connecting it to the secondary o2 channel is not good idea ...  And how to adjust the ADX formulas for boost and wideband  sensors?   Guys i apreciate you ! This topic is so full of valuable information. I kinda regret that i dont have your knoledge about programming.  Another quick one guys i tested the car and the Launch control works amazing although i searched the bin file and i couldnt find how to adjust it , make it a bit more agressive ? Thank you.

Hello Iksan !

I don't believe there's  such thing as "dumb people", but just... inexperienced people
What I believe is that, like all of us that reached a satisfying result in the end, you should read all the posts in this topic as they are full of information and effort from our beloved members. Trying to "skip" this is like skipping to the end of the movie and then complaining you couldn't understand why stuff is the way it is.

To give you a response still, I personally used another MAP sensor (The Motorola MPX450AP), glued it to the PCB with hot glue, and soldered wires from the VCC, GND and signal pins to their corresponding ECU pins (I used the tank pressure sensor channel) and my AEM UEGO WB tied to the rear O2 sensor harness (but took care that inside the ECU, the pin for the O2 sensor ground is tied to the ECU ground so I don't have any offsets in the measurement).

I cannot remember the pins from the top of my head, but you can get them here - http://www.villacarlota.net/volvo/motronicsuite/Volvo Motronic 4.4.pdf from page 7 onwards

Regarding formulas for the WB and MAP sensor measurement, you can simply edit the ADX file in TunerPro and set up your personal calculations there.

Just an example picture from the web, with a MAP sensor mounted on the PCB :

Hey buddy i apreciate your response . Im not trying to skip its just that i cant understand how are you guys coming up with those formulas for the map and the O2  im trying to wrap my head on it. Thanks for this file its very usefull i got all the pins that i need. What is that small switch for bud ?  Ya so the only thing that remains for me  is to figure those formulas and try to find how can i adjust the launch control because i cant find anything in the bin file . Thank you .

Here's one more thing that helped me through the formulas (the Motronic scaling). The rest is just converting what is measured (for example kPa) to what you want to be measured (for example PSI)

Regarding the switch, from what I've read on the forum where I've taken this picture from, it's probably been used for switching to normal / programming mode to be able to reflash it in the car. I've done pretty the same thing (included a switch in the ECU) but also added a step-up voltage converter so I can apply 16V on the programming enable pin.

FYI: I did a little write-up on how to figure out those formulas; converting volts to bits can be confusing for sure.  :a-farmboy:

The M44-scaling-RAM.pdf is a list I made from data in Vadis database files.

Vadis is using this data to convert and display live data from an M4.4 running vehicle through a Volvo System Tester or MultiTester Pro.

The A5 command is reading parameter numbers that are the same in all/most Volvo M4.4.

The corresponding RAM address is not always the same, so that column was added manually for one M4.4 specific bin-file.

The A7 command is reading RAM addresses directly.

Hello guys !

Even If it's off-topic, I wanna give my thanks to everyone who helped this proiect reach almost 500 pages (!!!), and wish all of you lots of luck, health and fortune in this new year, and even If we are meant to social distance, I wish to send a virtual hug to everyone out there.

Thanks for making VS what it is today ! Happy new year !!!

Hello! I am getting ready to flash my big turbo s70. Went to install emulator and had issues with the traces ūüėē pulpulled them.¬†

 

So going to go the flash route. I got the cable and am all setup. Went out tonight and hooked pin b8 to 14.5v and nothing happened. As far as i know it wont flash. I tried anyways. It says erasing then failed. As far as i know thats a good thing except it wasnt in boot mode. It definately tried.

 

I ordered a voltage step up from ebay. Is there anything else im missing. As far as i know you only need 14.5+ volts to pin b8. Which i did and nothing happened with fans or gauges. Etc. Im guessing just need a bit mote. Any advice would be greatly appreciated
