EMPEROR Posted May 24, 2012 Share Posted May 24, 2012 For the MAF, it might work, but this is definitely not the way you should do it. The MAF should use specific housing made for it. With exact diameter, exact opening for the MAF itself, etc etc etc. The MAF should go to a specific depth inside the housing and so on and so forth... As I said it might work, but it definitely isn't the way I would do it. Someone with better English might explain it better. Quote Link to comment Share on other sites More sharing options...

Ok,had it on 400 zoom too.you might want to get a longer bit of silicone hose, the clamp looks like it's holding on for dear life good luck with fixing the problem.

EMPEROR Posted May 24, 2012 Share Posted May 24, 2012 Yes this is the correct part number for the MAF. Although it's hardly readable on those pics. As for the information about the housing, you better check the stock one. Quote Link to comment Share on other sites More sharing options...

wewsupra Posted May 25, 2012 Author Share Posted May 25, 2012 (edited) right then here is part number 22204 20010 MAF ive read this on a web site about the above part running rich http://my.is/forums/f114/2jzgte-vvti-maf-407061/ some guy put this You can't use GE maf because it has small max flow than GTE one. I think you'll have too rich conditions all time. GTE sensor p/n 22204-46010 GE sensor p/n 22204-20010 but on ebay there selling theses for a supra with the part number i have got http://www.ebay.co.uk/itm/Toyota-Avalon-Camry-Sienna-Solara-Supra-Lexus-ES300-MASS-AIR-FLOW-SENSOR-METER-/221031817189?pt=Motors_Car_Truck_Parts_Accessories&hash=item337685dfe5 http://www.ebay.co.uk/itm/97-03-TOYOTA-LEXUS-CAMRY-SUPRA-GS300-GS400-ES300-AIR-FLOW-MAF-SENSOR-OEM-/320905051283?pt=Motors_Car_Truck_Parts_Accessories&hash=item4ab76e7c93 in this link this company sell maf for supra 22204 20010 http://www.toyotapartszone.com/oem/toyota~meter~assy~intake~air~flow~22204-20010.html what u think guys this is confusing Edited May 25, 2012 by wewsupra (see edit history) Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted May 25, 2012 Share Posted May 25, 2012 The MAF sensor MUST be the matching part number for all the rest of the FI setup, PLUS, you need to understand how it works. If you put the sensor a different distance from the ports to stock it won't work correctly. If you put it in different inmternally sized pipework to stock it won't work correctly. It will even work differently in different SHAPED pipework. So your setup hasn't got a lot going for it. You need to buy the OE pipework and air filter box really. That's aside from any wiring issues it might have. You need to be scoping the ecu signals to the throttle control motor ,and from the MAF sesnor, and to know what the stock signals should look like in comparison.

EMPEROR Posted May 25, 2012 Share Posted May 25, 2012 (edited) right then here is part number 22204 20010 MAF The link that SpeedyAndy game me for the MAF on eBay was on 22204-46010. That's why I said it's the correct one. If your part number is actually 22204-20010, this is definitely not the one for your engine! And except from the Flow Rate, this is pretty good reason why you must use the correct MAF. Taken from the link you gave: "I think the peep that brought this mod to attention here showed that the GE MAF is not designed with boost in mind, and does not have a buffer/shield/baffle to prevent "reverse flow". The GE MAF is 'blind' to the direction of flow, it just sees flow. So when you blow off, and have pressurized air actually moving backwards in the plumbing away from the intake manifold to escape out of the BOV, the GE MAF sees this as intake air and your OE ECU delivers fuel, bogging you down or stalling you out." in this link this company sell maf for supra 22204 20010 http://www.toyotapartszone.com/oem/toyota~meter~assy~intake~air~flow~22204-20010.html what u think guys this is confusing This is because you are looking at US market, and those supra's are NA VVTi. That's why the part number is the same. Edited May 25, 2012 by EMPEROR (see edit history) Quote Link to comment Share on other sites More sharing options...

spikedjack Posted May 29, 2012 Share Posted May 29, 2012 As i said earlier, i'll put good money on it being the vac pipes not piped correctly. I'll take a look tomorrow for you. Quote Link to comment Share on other sites More sharing options...
EMPEROR Posted May 29, 2012 Share Posted May 29, 2012 It's not the vacuum pipes as I got the same problem today. 5k top. I don't have both cats, so I am pretty sure they must be there. Will be able to tell more the next few days. Quote Link to comment Share on other sites More sharing options...
wewsupra Posted May 29, 2012 Author Share Posted May 29, 2012 thanks jack for looking i sure hope you can fix it as when i brought engine of yourself only thing thats diffrent would be the vac pipes like u said as we have not touched anythink else as you was running boost controller and i am not i got my fingers crossed and everythink else toyota want 169 pound for vvti air box (from japan) Quote Link to comment Share on other sites More sharing options...
EMPEROR Posted May 29, 2012 Share Posted May 29, 2012 It's not because of the air filter... Btw are you running rich afr? Because I am on high rpm. Quote Link to comment Share on other sites More sharing options...

EMPEROR Posted May 29, 2012 Share Posted May 29, 2012 (edited) What I have found over the net so far: "If that turns up nothing, try unplugging the MAF sensor in the intake pipe just past the air filter. If the car runs decently with the MAF unplugged (but it'll have a 5k rev limit and won't boost very well) then your MAF sensor is malfunctioning." This 5k thingy sounds just as my problem. Will try to unplug it and see what will happen. P.S. What oxygen sensor are you running?

SpeedyAndy Posted May 30, 2012 Share Posted May 30, 2012 (edited) hi emperor, I agree its not the boost lines. i followed the vvti diagram for the vacumm lines and If im correct in saying you only blank vacumm lines if you are adding a boost controller due to you trick the ecu ? i did take the first cat off and still done the same. is the oxygen sensor - that comes after the turbos into the little section of the exhaust before the cat ? or is that the lamber sensor ? VVTI Vacumm diagram - it was one of yourt posts emperor. It show the 1994 GTE engine and also VVTI GTE engine http://mkivsupra.net/vbb/showthread.php?250370-Can-anyone-tell-me-where-do-these-vacuum-lines-go&highlight=vvti+air+pipes Edited May 30, 2012 by SpeedyAndy (see edit history) Quote Link to comment Share on other sites More sharing options...
