That would be great Josh, thanks.

 

FWIR, none of the numbers in my Fuel Map are quite that low... but I might have some 9.3's in some spots near idle. I don't have "my" laptop back until next weekend, I'll check the maps for you then.

While we're asking about maps, what kind of timing retard are you using in yours? I had to push mine up to 6.5 deg. in some spots to completely eliminate ping...

 

Mine pings badly at low rpm's and even worse with the deck plate off. I'm pretty sure I'm really going to have to mess with the timing part of the map.

 

Ok thanks Brian. I haven't touched my timing map yet, so its still just as Gadget send it. So far I've had very little pinging.

 

It's not all that hard to do, especially if you can find a nice hill to induce ping on... Make sure and tune with the deckplate out, so you're tuning for the highest flow available.

Lucky you! My timing map wasn't even close, I had to stretch the area it covered and double the retard in some areas. I wonder if it's an altitude thing...

 

Humm.... I thought the altitude was suppost to help Maybe its all the up hill climbing you have to do?

Yes I was very lucky, Gadget's preloaded maps seem to be amazingly close for my truck. If it wasn't for going a little too rich in open loop I'd probably leave it alone.

The couple times I've had some pinging was right after I made a change to the fuel map but then it seems like the ECU makes corrections and it stopped.

 

I like the tupperware container lid idea. It sounds pretty innovative to me. Think outside the box innovative. Your woman might not think sharing her tupperware lid with you would be such a great idea though.

Just a thought.....
I'm curious about whether swapping out an A340H auto transmission for a rebuilt manual transmission would work, and if so is it cost efficient to just put in a manual transmission instead of replacing the A340H that is ready to die any time? What are you guys' thoughts?

 

Actually the 1 lb Vihta Vuori gun powder container is what matched prefect. See post #30: https://www.yotatech.com/forums/show...5&postcount=30

Sorry I don't know anything about the manual tranny swap, except its easier than the auto tranny swap. There are tons of threads out there on the manual 3.4 swap because that was all anyone did did for a long time. Until Team Shiftpoint did it with his autos and Mike @ ORS developed a kit for the auto and let everyone know it was possible.

To update with the FTC tuning, I just ordered this driver-visual knock warning system:

Hey thanks Brian for the tips and figures. The last paragraph one thing really jumps out as WEIRD. Your A/F is 12:1 while engine braking? Mine is more like 20:1 or even off the readable scale. I'd look into that, who wants to waste fuel while decelerating? Should'nt you be able to do a free air calabration during a long deceleration?

Does your ECU go into open loop very easy? Mine is making the switch to open loop at what seems like about half throttle sometimes, I thought it was suppost to only do that at about 80% throttle. Worst thing about that is I have a big jump to a rich mixture when it makes the switch to open loop (generally around 10:1-11:1)

I finally tried my new (to me) laptop that I got for $50 and I can report it works dandy at running both R4 and OBDII software at the same time. (Thanks Josh) Windows XP rocks. I'd now recommend NOT using any laptop with windows 98 2nd ed for tuning.

My water temps this week (70-75 deg days) have been running about 185-190 max so that's encouraging. I'm wondering now if I didn't have an air bubble in the system before.

 

Hummm... sorry to hear that. I haven't heard of any failures with them yet, have you? My 95 Taurus makes quite a whine whenever it gets below about 1/2 tank but it still runs fine. I just use the whine as a fillup reminder now. Can you hear it all the time or just idling?

 

damn fine write up, supa sweet build, and mad props to you guys helpn out. new member here but been readn up for months. excellent stuff mt goat. as far as your temps and fan issues...what goes in must go out(so to speak) is air having problems leaving your rad....essentially casuing a 'bottleneck' of flowing air? i dunno, just a thought and wanted to see if i could help on a badass thread.....prolly THE badass thread for a while to come.
oh and speakn of IC's mitsu evo's have IC sprayers that spray either manually or intermitantly a mist-O-h2o on dat der IC for colder induction....another after thought...but might need a heat disipatn paint/protectant on fins....i dunno....

 

Thanks for the kind words, I think I pretty much took care of the airflow out of the rad when I did this to the fan shroud:

Ok, I'm ready to try that TRD t-stat now. Yesterday we got a fairly warm day (83 F) and I took the wife for a cruise out of town. Going down the interstate with the cruise control set on 75mph, AC on all the way, stereo on etc... the coolant temps slowly climbed up to about 210-212 and mostly stayed there with the highest I saw 216 (all measured with the OBDII scanner). The factory temp gauge stayed pegged in the middle the whole time. Fan was running on high all the time at highway speeds. The boost would kick up to around 3-5 psi on some of the hills and the A/F ratio varied from 14.7 with no boost, to about 12 with 5 psi (with a nice smooth transition BTW ) EGTs were normal (around 1250F-1350F max), tranny temps 170-180F (measured right before the radiator cooler)

I ordered the TRD 160 deg t-stat this morning from Roger @ Bob Bridge Toyota ($36) https://www.1sttoyotaparts.com/partscat.html

For review, I currently have:
*URD (Napa) 170 deg t-sat
*New 3vz-e aftermarket radiator
*Taurus fan controlled by a DCC variable speed controller, wire run to the high speed side of 2-speed Taurus fan.
*I did park on a steep slope with the front end higher to get the air out
*Running water wetter with a 50-50 mix of coolant/distilled water
*Arrowdynamics of a brick and spinning 33" mud tires

While disapponted with the water temps, it sure was nice to cruise dowm the highway at 75mph without dropping out of overdrive for hills or headwinds.

 

Geez, mt goat; that was a d@mn fine idea with your fan shroud!! I love it.

 

Well thanks, too bad it didn't work a little better. If the TRD t-stat doesn't do the trick, I may go back and try the stock fan.

 

Hmm, I feel like we went over this before in some other dimension...

 

Is that like deja vu all over again?

 

so did you get a chance to install that thermostat? i am pretty curious what is wrong. i will say i think it is something else other than the thermostat or fan. going 75 the rad should be getting more than enough air; and for temps to be that far away from the thermostat's rating, something pretty significant must be wrong. i take it the motor itself is solid? maybe it is something as simple as a crossed hose connection, or even better just a faulty thermostat. let us know and good luck

 

Not yet, it's on order. Yeah the motor only has about 28,000 miles on it. What do you mean by a crossed hose connection?
