EGT probe for my EcoDiesel

[R.O.R-2.0]

pass axle is CAKE to remove. dont even have to separate the ball joint from the a-arm.. just comes out..

BE 100% sure to torque the BIG AXLE NUT to ~190 ft lbs..

if you dont torque the nut enough, or torque it too tight, it will mess up your wheel bearing.

Have to remove the pinch bolt on the ball joint to separate it from the wheel bearing knuckle? Is the ball joint shaft splined? Do I need to mark it so it goes back together the same?

loosen the axle nut, and loosen the 6 CV bolts. push CV joint up out of cup, towards turbo, pull axle out of hub, drop hub end out, pull whole axle away from car..

Thanks ROR!

Got it drilled and tapped! As it turned out, there was not enough room to get my cordless drill in there and get a straight shot, and had to resort to making an extension to the 11/32 jobber drill bit to make it long enough.

Here's some pics of the result and tools used, one of which was a small chunk of magnet taped to the end of windshield wiper s.s. backing to fish out metal chips. I used grease when I drilled and tapped but there was still a bit of chips in there.

those metal chips scare me, lol. I already purchased my el cheapo ebay EGT probe and gauge. I will install it on my NA exhaust OFF the car, and I will install it on any turbo exhaust I get before installing it on the car

those chips scare me also, so I went in there and fished  around a few more times to get more chips out till it's all gone.

 I  finished the install and went for a test drive. works great, instant response! real happy with the results.

 took a video, 64 megabytes. will upload later when I get a wifi connection.

so, start the engine, the only way they can go, is thru the turbine, witch is harmless, its not going to even be spinning when that first exhaust valve opens up and lets a puff of exhaust go thru the manifold.. either that, or the metal is going to go back out the hole as soon as the engine fires.

so, if your worried about it, drill it with the engine running, then the exhaust PUSHES the chips back out of the hole, they never actually make it into the manifold to go thru the turbine..

Here's the vid! Sorry for the moving cam, it's mounted on the steering wheel. I was starting from a standstill getting on an expressway on-ramp and went through all 5 gears. You can see the boost gauge on the right and the EGT rises and falls in accord to the boost gauge. The last shift to 5th I stomped on the pedal (got smoke) and the EGT went up to 1243F and boost was at 10 psi, the max it will go.

Should I adjust the wastegate for more boost? Add a MBC?

I've read many places not to mess with the wastegate to just add an mbc.

DONT FU** WITH THE WASTEGATE!!!

buy/build a boost controller...

Do you know why?

vid looks cool I hope that my $30 ebay setup works as well. whats the blue light? come on at a certain temp?

Blue light is an alarm set at around 900F. It's programmable and I will set it higher and also hook up a buzzer if possible.

Picked up an ACN with 138K on it today.

I put on about 350 miles since the EGT gauge install. Going up to the Catskills, the Palisades interstate parkway and 9W has a lot of windy hills, a beautiful drive! EGTs were anywhere from 250 to 1100F depending if I am going  downhill or up, how steep and long the hill is. If I gun it, I can get it above 1250. One interesting thing was that on a downhill stretch, EGT is higher if I put the engine in neutral (400F) than if I coast in 5th gear with my foot off the pedal (250F). Could that be due to more cold air intake due to higher engine RPM coasting in 5th vs idling?

The pump quits pumping when you let off in gear over certain RPM for sure around 3,000 might be even lower. Even lower rpm it will be less fuel than if you were accelerating at the same rpm or holding steady, if it isn't completely shut down already. At idle it still has to feed the engine to keep it running, so with that fuel still coming it doesn't cool as fast and should be less air moving also as less rpm.
