TURBO INSTALLED ON 1SZFE - Page 2 - Toyota Yaris Forums

so you think 10.5 is rich ?

Focus_Sh1ft · 11-16-2010, 01:38 PM

I definitely agree, 10.5 is too rich.

11.5 is mostly accepted to be the money spot for FI engines. I'm amazed you're even running at all that rich, as I recently had a problem with my tune where it would drop me to 10 and the engine would stutter BADLY.

I set my tune up to reach 11.5 by 5 PSI of boost, and linearly approach it as soon as boost is entered.

Anyways, congrats on the install. Could definitely use some cosmetic work though

lol ok
well could you answer my question which ive asked in this topic regarding o2 sensor

Focus_Sh1ft · 11-16-2010, 05:39 PM

I'm not entirely sure what you're asking, but here's my experience with our O2 sensor:

I drove around for about two months without a tune, letting the O2 sensor handle all the fueling. While in closed loop, it was always successful of maintaining stoich, even while in boost.

Eventually something strange happened, whereby the ECU threw the car into open loop at all times. No CELs or anything associated with it either. The car would quickly lean out during boost (I saw 15+ and it was continuing to climb), so something had to be done. I decided to just pull the O2 sensor and tune the car in open loop. Worked like a charm, drives great, and is very tunable.

In retrospect, I think what happened was the ECU was witnessing negative fuel trims (adding fuel) that exceeded the malfunction threshold (-20%). As a failsafe, it determined open loop should be used. I'm not sure why it didn't throw a code though (however P0101, the code I did have at the time, does have a connection to fuel trim - so that could be it). I could have tested this theory by resetting the ECU but said screw it and tuned the car in open loop instead.

well thanks for sharing your experience i think o2 tunes itself so id let the o2 control the fueling

I said to myself yesterday, the word "topmount" is like bait to Tamango & sure enough he strikes again.......

Its CDYDJDED, now that that's cleared up, Im sure you topmount worked great. Im sure others have failed. I would just like to know of 1 company that sells a I/C that goes from front mount to top mount. I can find many that go from top mount to front mount. I just find it amazing that you cant accept that the majority of turbocharged vehicles use front mount systems not top mount.

subaru and toyota use front mount.

toyota and volkswagen use side mount.

when i turbo the MR2 i'll use a heat exchanger front-mounted for my water/air cooler..

some things make more sense than others.

I think I stated instantly My mind was working backwards for that molment and retracted that statement. You Ass-Tard

Come on guys no threats. They gonna think all of us Fl guys love to fight lol

xbgod · 11-19-2010, 05:03 PM

Thats not a threat, thats wishfull thinking.......

Wow, I got no Turbo, but I'm reading this thread just for the entertainment! :)

Top mount would be preferable on these engines. I mean look, some people even ran WITHOUT an intercooler, for some power it's okay, but for what people were trying to do was trying to squeeze max power from a non intercooled engine. Always want to intercool to take away more risk of detonation.

With that being said, why would you want to run an extra 4 feet of piping to the front and back around the engine for what? Pressure drop? Easier to hack up a $100 hood and make a proper cooling duct for a TMIC than to mess with shaving supports in the front or frame work. The tmic depicted is perfect for this application.

Also ive been tuning a few DSMs lately, running as rich as 10AFR and as lean as 18 at cruising and 30 at idle. Needless to say i fixed that issue quick. 11.5.7 12.2 at wot. cruising and idle is around 14.7, 15.2.

The more common UEGO gauge reads only to 10-17, 10/10.5AFR being the lowest i would allow a car to run, yes rich, but i don't think rich enough to mess up piston rings or anything. The kids been doing pulls all year on his stock pistons, no issues ever.

Faraz_Shaikh · 11-20-2010, 03:46 PM

thanks for clearing issues nexus
id like to draw your attention towards my question regarding o2 sensor, could you please clear up issue

car was not getting tuned by earlier , i used to disconnect o2 sensor so the car used to get rich, without boost like below 3000 it used to be very rich and as the turbo spools it used to be perfect, and if i used to run car with o2 sensor so it used to be lean all the time but like for 3 days i didnt disconnect the o2 sensor and used to do normal cruising but yesterday i made a try, i ran car with the o2 sensor the car was perfect, in all 3 gears it was perfectly awesome. i asked my tuner he said your car has been tuned automatically via o2 sensor.
Later i made another bunk next to o2 sensor for checking the afr, the afr was 10.5 to 11, when i disconnected the wideband sensor from that bunk the car again was in old situation, was in lean with o2 sensor so now i have again closed that extra bunk in manifold which i made for checking afr and now o2 sensor is connected.

So now my question is that will o2 sensor again tune my car automatically and control the fueling accordingly ?

This thread is full of douche.

OP - It should...what you are describing sounds like the ECU going back and forth between open and closed loop modes, so if everything is plugged back in, it should take back over. Also, you don't have to remove the AFR sensor you added, as it should not interfere with your O2 sensor.

As for your install, it's a mess, but I'd imagine you probably don't have the resources there that we have here, so congrats on getting it together and running man. Keep it up.
