I had similar problem on n52. Fucking PCV failed, and I guess due to the engine shaking its ass off it kept throwing cam-crank correlation had that too, fix it, no change on the cam sensor issue....its usually just the sensor but on a high miles engine it could also be a plugged up oil pickup. Must...

Well, I've driven it what, 40 miles a week ago? It's in rough shape but at the moment I do not have time to even hook it to laptop :( Steering warning light, check engine light I think Sergey said CAM sensor error and timing chain issue is worst fear, air suspension leaking etc etc. I had a cam sen...

The gauges are to help sync the TBs, they read % error from TB12 which is where the actuator is attached so it is always 0. Here it is after I played with it a bit, not prefect but much better. TB sync2.JPG the graph below are the cylinder MAP reading that run the gauges....this looks to be working ...

I tried resetting the TBs with feeler gauges this morning as a base sync while also playing with the ECU software to try to read them all....the feeler gauge method is pretty bad it turns out if my ECU programing is to be believed and this is after a couple quick roughing in adjustments. he linkage ...

Wait.... It's running.

I know, right?!? LOL

Running, a couple 6-7k throttle snaps and 2k idle...pretty rich but running.

Personally, I would always prefer a MAF sensor over a MAP sensor. Precisely because I get directly, always and under all operations, the air mass that the engine is currently taking in. I do not have to correct, adjust or anything else, just directly calculate the injection quantity for the desired...

yes! no bad noises, lots of oil pressure, no real leaks, so good so far other than an erratic fuel pressure. I'll get some more gas in the tank and see if that clears up that problem and then try to keep it running....tomorrow's a new day.

I put the plugs in then spent some time trying to get the boots to right right and the wires resembling neat 20211203_095854-resized-1024.jpg 20211203_095906-resized-1024.jpg 20211203_105955-resized-1024.jpg As long as I was making stuff a bit neating, I gorilla taped over the hack job I did on the ...

This is a challenging assembly.  I didn't have room for 2 fuel rails  or to assemble the rail to the TBs then drop the assembly into place so assembling relies on everything flexing enough to pop into place. 20211201_204657-resized-1024.jpg I decided the rail wasn't sitting just right and was torqui...

Congrats on the R&T article!

Is there something new or is this the old one? I see youtube views on an old video all of a sudden coming from R&T but a search didn't find anything new?

guys, how about MAD, or Manifold Air Density? pounds of air, instead of pressure(resistance) or flow(g/s) hmmm....if you know the IAT and MAP you can calculate MAD and that is what is done for speed-density math but that is not enough as you need to know the mass of air in the cylinder, so then you...

Trying using speed density on something like a gasoline engine with a variable geometry turbo. You know when the engine can have drastically varying ve at a constant manifold pressure/rpm. I've never run into that setup. I was talking about NA where even small pressure drops in the intake matter so...

Just like its nearly impossible to find TDC with a dial indicator by looking for the top, I expect you'll have the same issue only worse with a pressure gauge. If you run a high speed log and and pick a point , say 100psi before and after TDC, then TDC will be ABOUT in the middle. With a dial indica...

The new fuel pres sensor is much better, 71mV offset and seems stable.  The oil pressure still reads 0 with the 270mV offset so it appears stable.  The manifold o-rings came yesterday, I bought 3x8mm instead of the standard 3x14.5mm to make it a little easier to assemble and they seems fine.  Just w...

Wow it has passed salvage inspection it's "GOOD" to get rebuild title and plates!

Congrats! It looks like you'll be driving before me.

Pulled the intakes and rail off, nothing obvious but the o-rings are generally sketchy to ordered new. When I was cranking the engine to prime the oil pump I noticed I had like 10psi oil pressure and thought it fine....but then noticed I also has around 10psi fuel pressure with the fuel tank empty a...

Had oil lines swapped to the filter, that took some time and a bit of an oil mess to sort but there is now 20+psi cranking - check fill the coolant...hmm..nothing going in....front down, back up and 3 gallons in the last 3 were a waiting game while the thicker Evan's stuff leaked passed the pump and...

Put the cap back on but that was not the issue...it was the tach pulling too much power on the 5V buss so the tach is off-line for now to the throttle is back on. A couple other little oddities...cranking I see about 10psi oil pressure which made me happy until I notice I was also seeing about 10psi...

get this thing running.

and then driving

Drive it? What kind of crazy talk it that?

...hopefully that day will come. Today ended with no throttle...I finally found a cap off the driver board so hopefully replacing it will solve the issue and it will run tomorrow.

Spent a lot of time today fixing the car I broke with the stump removal project (yup, ripped the hitch off) but that did give me a chance to push the ferrari out and get it turned around so if it again becomes a flamethrower it will be pointing in a harmless direction.  I also pulled the radiator an...

alternator, axles, and exhaust in, coils and wiring next then systems checks while I wait for some hoses and clamps to arrive I guess.  Oh, need to pull the radiator and be sure the water based stuff is all out and the battery is shit at this point so I need to grab one of those too.

Oil lines connected, they look like spaghetti, which I guess is appropriate?, oil filled and system primed, and the oil seems to be staying in the engine so that's good 20211122_193109-resized-1024.jpg Went to install the alternator..oops, water pump first...oops, this hose really should go before t...

here we go! 20211120_171605-resized-1024.jpg I figured out I could install the headers once its part way in WAAAAY easier than once its actually in 20211120_180152-resized-1024.jpg and in the the car, not bolted but in at least. 20211120_185722-resized-1024.jpg 670lb with everything that attaches to...

and that is it. Tb's and intakes installed

This morning did not go exactly to plan.  First, I had calculated my vacuum hose lengths to work out perfect with 10ft rolls, but after I started cutting I realize they are called 10ft, but are actually 3m, so 2" short....delay to figure how to get things sorted. ok, time to...wait... 2 injecto...

Did a little.   The bearing is replaced and gear drop gear cover installed and cover straightened out, it on easy as normal.  The coolant manifold is on.  The oil pres senor is back on. 20211119_192644-resized-1024.jpg I cleaned up the TBs and intakes so they are ready to install...but that is not a...

clutch, starter cam end-covers cleaned and installed 20211117_204614-resized-1024.jpg Not exactly what I planned to do.  I planned to part the vee stuff on tonight so I could do TBs tomorrow because I like to look at it with TBs on but it was not to be.  First I realized the way the temp sensor was ...

I'm not sure if I completely understand your concern. The output of the header is 2.75 inches then there is a reducer that adapts to 3 inches after that. Would the collector need a restriction afterwards where the dia reduces and then goes back to 3 inch with a taper? What would a choke implementat...

stumbled onto this today.....a V12 308 that actually runs, crazy!
