Hey guy just wondering where about a should be looking to find a 2 bar map sensor, and also a tune for it?
I need one so i can up the boost on my CRS setup on the vp.
Cheers.

i brought the 2 bar from there, works good you need to modify the connector tho (cut some grooves in the plug)
tune isnt easy because the 2 bar reads diffrently to the 1 bar, ie the car WILL not start/run on a 2 bar without a retune... also the map readings are at diffrent intervals ie, 2 bar reads 40-60-80-100-120-140-160-180-200, i reckon you get the idea... map 100 being 0psi, and map 40 being around 19inHG vaccume, map 120 being 2.9psi boost
ask greenfoam, after all greenfoam developed the definitions for it yet no one gives him credit..just rips off his work :P imo
shouldnt be too hard, VN_Luke had his tuned to perfection, also stocky runs a 2 bar CRS setup @ 10psi
and if your running stock injectors/cream/blue tops ill bitch slap you....
I never made the VN 2bar it came from a dude that made a twin turbo 350 chev in a Camaro or something but I don't know if he made it either. I just made the VR manual version. It's not hard to get any boosted car running perfect on the 2 bar though if you go about it in a common sense way. Tune rich and with mild spark then back it off slightly then increase your spark, you should be able to feel it stamma a bit on the knock sensor if you go too far on the spark so then you can come back a bit and then it will be done and perfect and make just about ever last rwkw it was ever going to make
the knock sensor only works upto 3500 rpm so after that theres no knock control so keep the higher rpm timing low as the engine is too noisy after 3500 to sense knock so its cut off in the tune

hey greenfoam do you have much info on the patching of the code for this $5D 2bar tune seems the aldl doesnt work properly strange figures output O2 volts wernt right and heaps of other odd stuff so no logging with this tune without a lot of work any ideas any info glandy accepted had lean malf flags going off but its clearly rich .like black smoke rich
The base code on that binary might have been changed man, but if you use a stock 5d binary and swap all the settings from the 2 bar 5d onto it you should be fine again. I don't own a laptop so I can only tune by smoke and speedonce I make the best possible run on the gtech I know my air fuel ratios are perfect
. Black smoke is 9:1-10:1 so once you make that you only need to remove 10-20% in that section of the VE depending on how well that engine is cooled and its right on the money, if it pings remove some timing and or add some fuel to cool it down :P. And add your final spark untill it feels "crisp" that's how Luke tuned his blower and turbo to perfection and how I tune my friends Silvia on 14 psi. Luke turbo was running 10 psi peaked out all day drifting at Calder park with no intercooler (I'm impressed with that, not many people can make a uncooled turbo run that well on 10psi
). Old school but it works. A wide band would help you get there faster but I figure once your going as fast as it can go then it's perfect anyway no matter what the wide band or dyno wants to tell you
yips its patched up to all buggery things like the coolant spark advance im wondering if this could now even be mat spark advance now but probably not theres a fair few things changed in it makes it hard too see what the ecu is seeing there was lots of iac counts up near the 100 mark should be low shouldnt it
I've seen a few of these 2 bar map sensors to suit VN/VS 1's on eBay(yeah, I know.). The seller reckons you can do a straight changeover to stock engined(Uncharged) car.
Whats your take on them??
I'll just check that 5D to see if the code is changed,
Nah the actual program on the 5D I've been using for 2 bars is the same as APNX, on the binary you are using in the difference tool on tunerpro do you get blue stuff (outside the defiintion) that is different on the difference tool?
I know defa got a 2bar from somewhere and it ended up being a 1bar but the guy was more than happy too give him another one in its place
nice one greenfoam hex aint my language .This was part of the reason i am working on the $58 code have you had a nosy at the 58 tune i posted it would be good i reckon if we can get it going
sorry about raiding your thread 10000_fists its bumping your thread up the top of the list though
hey greenfoam what about max timing advance i heard this and the reference had to be set like standard vn to get the dwell right for the dfi to stop it from burning out or something stupid
I've only had a look at it ages ago before I had my VP and didn't know about the 2 bar on the 5D, I was going to buy the ecu though and run that on a turbo V6, since the wiring was a bit similar. I didn't know it would run on the 808. The ecu's for them are cheap on ebay though!![]()
yeah i thought the same but it must just need to be added elsewhere i dont really know i think i posted the info about it in the $58 thread 129 american + 70 for core charge plus 10 postage for a 1227749 ive just found something about the netres that might be why ive been having trouble im not gonna post in this thread anymore seen we are off topic in going to add 5D tuning into the $58 thread if anyone wants any info sorry 10000_fists you can have your thread back now LOL
Hey thought i'd post in here instead of making up a new post.
Just wondering if i get a 2bar map sensor c an i chuck it on my car while i have no boost running and jus the stock tune? Just wondering cos i have the charger off at the moment, i was hoping to put everything on that i need(injectors, map sensor, hi flow fuel pump and rising rate pressure reg) so that i'm ready for when i get the charger back on.
When the charger is going back on it'll just be running 3psi for a few weeks till i get the intercooler running.

what ignition timing are you guys running, my tuner locked mine at 28 degrees
Mine is stock as so wouldn't have a clue. I haven't got a tune done yet, waiting till i've got the 6 psi pulley ready.

I'd love to find out the answer to this 1 too for later down the track.
Anybody know if they're any good??
