M4.4 Remapping.......

[oblark]

wow thats a big difference!! just a little leak huh? glad you sorted it mate

I`ve got to refit the greens and check the readings, if they stay at or near zero then I have to try my bin file to see if it was a leak or a corrupt bin file.

All will be clear by the end of the weekend

well ive got my fingers crossed mate

[Dangerous Dave]

Cool, nice one!

Another problem solved (hopefully). Its great to have all this experimentation otherwise we would never find these things out.

Bring on the COP conversion!!

Thanks,

The ECU for the COP`s is being sent off shortly to have the resistors fitted

Awesome

Must get me a spare ecu, have some more playing to do when I get the time.

Had a spare 5 minutes last night so I load on white/3.25 maf bin file and the LTFT_PL went mad, When I checked the maf table for that bin file I found that that the voltage to air flow where all over the place. So I made up a fresh white/3,25 maf bin file and loaded that on the car and the LTFT_PL where back down to almost zero so it looks like I`ve been using so corrupt maf table files. I spent a good few hours last night going through all the 3.25 maf bin files and deleting all the corrupt ones.

Next step is to refit the greens and set them up so that the LTFT_PL is as close as possible to zero which I plan to do after work today as the weather for the weekend down here looks like it mite be a bit wet.

Had a email from Maarten who has finished making/testing the box of tricks that will enable to log extra channels so I`ll be able to log, oil temp, oil pressure, fuel pressure, pre & post intercooler air temp and exhaust gas temp.

Good news then

I had a problem with a corrupt file which kept cutting out as soon as the car moved, would idle fine. Did a file comparison and found that the speed fuel cut was set to 0 so as soon as it detected a vehicle speed the engine died. God know how it got changed as I wouldn't even touch that setting. All good once that was found out.

Well the green/3.25 maf was loaded on the car this morning and went for a drive to dyno at Gosport to rebilud the cooloing fan motor, then on to the breakers to get Grahams timing belt cover, logged the whole trip and I can report back that I`ve now set up the greens with the 3.25 maf

On to the next problem.......



14 psi of boost at 3000rpm

[Dangerous Dave]

Nice one

On to the next problem.......

14 psi of boost at 3000rpm

Thats ok isn't it? From what I've read on the WothR website about 1bar at 3000rpm is ok/maximum. You got standard rods in?

[oblark]

You got standard rods in?

Yeah, I`m running standard rods.

I`ve found out that to overcome the boost at 3000 rpm I need to lower the TCV set point

[oblark]

Pick the fuel rail up from the fabricators after they have welded a 1/8 bsp bung in the end and the extra logging device arrived from the Netherlands

where does the extra channels box wire into Rob ??

[oblark]

It just needs a live, ground and tapping into the K-line which I`ll either do in the ecu or by the OBD2 socket.

In your other thread, I've put how to wire in the OBD2 port

The thread about converting a obd1 car to run a obd2 ecu is for a mate who wants to see if it possible to do

My 850 is obd2

Was interesting, as you have an Ostrich!

But, that is how you have to convert a pre-obd car

(Mine is pre-obd)

Went to the local piston head meet this evening and it was an ideal time to try turning the boost down, so I loaded the TCV set points for 19T.
Well I had to ring it`s neck to get 7psi of boost.
So I loaded the TCV set points for 20G and she went like a rocket on 11 psi of boost, most of the time I ran out of road

At 50% throttle I had, a maf voltage of 3.14v(5v max), 595kg/hr (1603kg/hr max) and a injector duty cycle of 57% still plenty of room for expansion

Love it, and just on 11psi!

Where did you get the setpoints for the different turbos from?

[oblark]

This little bad boy arrived today .....



Here is the oil temp sensor with its adapator to fit in the drain plug hole.



Stared wiring the logging device in, the oil pressure sensor was fitted when I changed engines over.



Hopefully the 2 thermocouples for the pre & post intercooler temps will arrive by the weekend and I can get them all wired in and running

[caseyt5]

I think i'm the only idiot that cannot work out how to use tunerpro and motronic suite! Looking good tho Rob when you bringing her out or going to any meets?
