Far out man. I'm not reading all that I've heard too much about it already.

In your remapped ecu, can your consult read all vitals and logging and stuff that a PFC could? Log Errors, dead sensors and stuff?

[WogsRus]

i told you it would take 2 days to read. LOL.

yeah i have nissan datascan, and no errors what so ever. The car appears to be opperating normally with no issues according to the computer.

Go figure.

I would just like to take this moment to brag and say i got just under 500k's to my last tank

but i also ran out of fuel and had to fill up a jerry can... it was also 5th gear boring driving for most of it

[RBwhatever]

Fuel Filter? Probably doesn't have anything to do with it but anyway....

I'll give the fuel flter a try, was replace 10k or so ago.

after you take it out, cut it open and have a look inside.

[WogsRus]

will do, maybe the injecotrs are cloged to kindom come. I have also replaced all the fuel lines as i went allong, so i don't think it's a leaking fuel line.

17mm Hg, my 33 idles at 20 - 21 mm Hg, and so do a shit load others I've seen...

Sounds like you have a vacuum leak somewhere personally.

Also, ditch all the little tuneable things, and get one big tuneable thing.

As much as I'm not a fan of the PFC, you should get one.

You should use one device to control one element, at the moment you're using 2 devices to control one element. Not smart. They tangle each other up.

That and you may have lost your map in the SAFC

As much as I'm not a fan of the PFC, you should get one. - That's because you can't tune them properly

That and you may have lost your map in the SAFC - SAFC's are shit to tune.. they are very rough.. you can never get those flat spots out of them.

[WogsRus]

ever since i have had my car it has ideled at 17mm of HG, and i have tested every part of the car and found no leaks at all.

The compression is 150 psi across the board and 2.5 psi leakdown results, so motor appears healthy.

I have also replaced the PCV and so forht.

Map still in SAFC checked that, plus the safc is not doing much as teh map on the chip was preatty right on.

Oh did i forget to mention Tune ?

[RBwhatever]

I suppose you should just run it on the dyno with the wideband in the exhaust to tell you what you already know....that its rich. Once thats established, retune to the correct AFR's across the map. So yeah, as Guilt-Toy says, Tune " " " " ".

Maybe an FC is worth your while...? If your not happy with it, then sell the FC(they go for a hefty price) and plug the remapped stocker in again.

It seems your running out of options. You've done and replaced just about all the known possible physical causes, If its not that, then maybe the ECU is not functioning the way it used to anymore. How many degrees of timing is it running?

Well PFC are esentially what i have but the chip is a hell of a lot more expensive, my chips cost $5 ea and tune time,

who cares if the chips cost 20c. you said yourself no-one on your island tunes them so it's not much good to you is it? i mean you are using a cheap signal bender to run your car and wondering why you have bad economy. I would say there is two reasons for the poor economy.

1. driving condition/driving style

2. tuning

you don't have to buy a power FC if you don't want it, but it will be doing a much better job that what you have now even right out if it's box.

[Adriano]

Have you considered NISTUNE, its real time tuning for the stock ECU, $200 http://home.aanet.com.au/nistune/

[WhitePrincess]

had an oxygen sensor on the dump pipe replaced in mine which added 50km per tank. the car was running rich all the time. when you look at it via Consult and rev it, it suppose to go 'rich, lean, rich, lean' apparently

good luck

[WogsRus]

yeah the 02 is fine.

OK I'll sat it again. I DON"T WANT A PFC. thanks.

thanks all i'll see what the tuner says

[WogsRus]

OK OK OK

So i sprayed 2 full brake cleaning cans all over the hoses, connectors all over the engine, anywhere where air could leak, and i do mean everywhere.

AND nothing, no leaks that i could find at all, and the vacuum is still 17-18mm HG no more. Unless the guage is dogie, also i amm pulling it form the hose that goes to the charcoal canister, may need to re rout it.

[RBwhatever]

Was that while the car was running that you were looking for leaks?

[RBwhatever]

did you pressure test the IC piping and plenum for leaks?
