That's alot of oil pressure 
About right for a Serp at 2.5k RPM + looks to be about 55 
Finally got Neal1980s old turbo motor running very nicely in my Chim (apart from my slight leccy fault- see other topic) and all the other bits of car put back on. By christ it is quick!
Only thing is it seems to be running circa 1.0 AFR too rich when up to temp when compared to the AFR table (AFR, Spark and VE tables pulled from Neal's old map). This is with the car static and trying the engine at various revs. At tick over I am running about 11.5 AFR to get a good idle - no stepper motor. Any comments on what would be an acceptable AFR?
Glancing over while driving the thing also seemed to indicate circa 1.0AFR rich, but I need to work through my datalogs and trying to look at 2 x PCs while the turbos boot you into next week is a little challenging.
I was trying to get to the AFR ratio in the AFR table (12.9) by reducing the values in the VE table (just playing really as I have not much of a clue on this yet). However, this screwed up tick over and caused hunting
In fairness the car runs nicely as per Neal's map so next step for me is to fix leccy fault and get in on the rollers with someone that knows what they are doing! I also want to check that my WB is telling the truth -(Did a free air recall which made no change so assume it is). Also
While I think about it, what the hell is 'Advance Bucket' gauge I can't work out what that is telling me.
Neal if you are reading this I will give you a bell for a quick chat some point this week once I have a few more Data logged runs and I have re-read the basic MS stuff.
Anyone know any good MS mappers around Andover/Newbury/Salisbury/Swindon way?
Just got myself a Defender as a tow car - thing is it has no engine yet so might be a few weeks until I can ferry it somewhere.
Cheers, Matt

The AFR is only a target ,if you have a lambda guge check it next to the Tuner studio it may be a ground problem ..When I`m on cruise at low load my afr target is 15.5 the tuner Studio shows 15.5 but the lambda guage shows around 14.7 .So there must be a ground problem ..
Mine idles nicely at around 13.8 to 14 afr.

Glad all is up and running. Give me a call anytime..sorry only picked up your email today as well. I do have the exhaust still and its sleeved, If you still need it let me know.
11.5 idle sounds quite rich to me lol...what wideband are you using Matt??

As far as the shunting goes, rich ending it up improves it, that's what Austec did but Shaun had a different approach.
He set the AFR back to normal and reduced the advance on the ignition timing at that point. The shunting I had was completely lliminated.
Happy to do the driving Derek and share my map.
Can you email me your msq..He set the AFR back to normal and reduced the advance on the ignition timing at that point. The shunting I had was completely lliminated.

Err, possibly Daz, you are asking a Luddite though!
Just save your msq ,name it something then send it via email.. you need to keep and copy in your files..After speaking to a guy at Chatsworth I`m going to take his advice ..I`m going to get rid of all the rubbish wiring and get a loom made and fitted ,it`s going to cost but it`s a waste of time me doing any type of tuning before hand .
The big problem is the original installation is hideous ,I have even found the lambda cables wrapped around the heater pipes in a knot ..
It`s a task to remove and get one made up because some of the cables are to short and some miles to long ..If I boot the car the two wires from the trigger wheel sensor pull out with the engine movement ...It`s a bodge..The cables route in all directions .

I think you do right Daz. If you are prepaired to make the new loom yourself you will save quite a bit of money. They are pretty straight forward really. Have a look at Phils sight. Extra efi, there are some excellent diagrams on there showing you everything you need to know about how to make your new loom.

The main problem is the cables come through the wrong grommet just left of the windscreen motor ,they need to go through the correct one .The cables are all over the place .. How can a loom be made for me if the one I have is not the correct length..
I always make bespoke looms .. you never know what you're going to come up against in an engine bay, people move things around, TVR moved things around. You need to make it wire by wire and get them all the right length from the start. There are generic looms on the market but I wouldn't buy one. Start from scratch and make your own.
As Jools says, if you want it right, neat and tidy you will need to run each wire to the correct length. Buying a loom already done will probably still mean some alteration if you want it right.
There`s nothing wrong with some wires going through the side gromet by the wiper motor. I have just made my new loom and have run all the sensor wires through this side gromet. Running just the injectors and coil packs through the main gromet. This made sense to me keeping the sensors away from electrical noise ie. coils and injectors.

Your voltage table will be out, check the instructions for you afr gauge it should give you the correct voltages for you to put in to MSMine idles nicely at around 13.8 to 14 afr.

Ref: your afr and ignition at idle, mine likes 13.7 afr and 13 degs.Only thing is it seems to be running circa 1.0 AFR too rich when up to temp when compared to the AFR table (AFR, Spark and VE tables pulled from Neal's old map).

Also if you have interpolation on the cells around the cell your looking at will have an effect on it
Edited by Discopotatoes on Tuesday 30th April 22:09
Thanks Disco. Working from Neal's old map I have an AFR target of 12.9, 12 deg advance at 700RPM/10 deg advance at 1000RPM
I am getting circa 11.5 AFR at running temp
I have already backed out the WUE enrichment as it was running so rich at cold start it was fouling the plugs.
Just seems strange I have an identical set up to Neal and getting different results. I will double/triple check the setting again. I am running a later firmware on MS2 to need to manually copy his settings from Megatune into my Tunerstudio map.
Over the weekend I will have a play with the VE table to see if I can get closer to the AFR target, but ultimately I don't have 100% confidence in WB reading so really need to get this checked out first.
Also don't really know what I am doing
