Give that engine a rev!

 

I know what you mean! I understand the basics of an engine, but when you guys start with the wiring/electronics, I'm lost!

You might be the first 2.4 swap in all of Europe!?

So what's that differential pressure sensor for? Surely it measures the pressure difference between the inside of the fuel thank and something else... but what? And what purpose does it serve?

You guys are going so deep into the workings of this car that even I don't always know about the stuff you run into!

BTW Diavlo, you might want to use heat shrink on that custom wiring of yours... down the road that electrician tape will tear, degrade, get all sticky and messy and not protect much if at all. Heat shrink will probably be there for life. It does make your cables look like factory items too... Then again, if you've already put something at both ends of the cables it's not an option anymore...


Keep at it guys, I can almost smell that new engine odour from here... you're doing great and it's a blast to read about too!

It senses the difference in pressure between the inside and outside of the fuel tank. It's part of the emissions control system.

 

Today we did the front camber bolts and axles.

Camber bolts were easy! Left axle was easy, went in no problem.

The right hand axle however we could not get it as it would not push far enough into the transmission. This may be because in order to combine the inner shaft with the center bearing we had to hammer the end were it fits into the transaxle.

Basically we think the spline ends may be slightly damaged from hammering which is stopping it going in.

We have put the axle in the freezer overnight which may help make it a fraction smaller.

Hopefully we can get it to fit tomorrow. Its been a nightmare today. Any ideas?

 

Today.... it became alive!!

And yeah, we have a video that we'll post later!

Basically - it started, and ran on the 3rd ignition attempt.

A few things:

1). It is EXTREMELY LOUD - so loud its probably VERY illegal to drive!!
2). The RRM header and exhaust surface smokes bad - is this normal?

And heres the thing we need to know -

The engine idle is very rough - its at about 1800rpm - anyone know how to drop that to about 700rpm?

And the engine makes quite a few ticking noises.

We currently do not have the fuel pressure sensor connected, the fuel temp sensor connected, the fuel level sensor connected to the ECM.

We also connected the ignition coil power wire to the 'ON' live for the fan control ECM - as it was the easiest option to connect that to.

I've made a video of the noise it makes so can you guys check to see if its normal.

Im sure there are some bugs with it that need sorting - but it hasnt stalled yet and revs instantly.

Oh, and by the way - we are over the moon.

Now all Carl (solouko) wants to do is go out, get hammered, get stoned and then do something to celebrate!

 

We also were wondering if the engine should be reving itself a slight bit to let the ECM learn - as this is the first time its ran an engine - what does the ECM do to learn - basically we just want to know what to expect the engine to do at first start up.

 

I would at least get the fuel pressure sensor hook up before you try and start trouble shooting any ideling issues, the ECU is most definitly not seeing the correct pressure so its going to try and compensate same goes fro the fuel temp sensor to a lesser degree.

Good luck on getting the bugs worked and to a job well done. Its been very entertaining and informative following the build.

Congrats!


If I remember correctly, I had to allow it a bit of time before the idle dropped to normal when I reset the ECU... there's deffinitely a learning period. I don't really remember how long it took... surely not days, but more than a couple of minutes for sure.

Congrats on at least getting it Alive :thumbsup: The hardest part is done I would think!!

 

Excellent!

2). That's normal.

I have a video I shot of mine on a cold start. It starts out with a smooth fast idle, gets choppy, drops rpms a bit, then blips the throttle and smoothes out the idle, then drops to the normal 750 or so. Let me find it and link to it.

Here it is, Quicktime format, ~8mb. Right-click, save as

Never mind my neighbor. He wandered over while I was setting the camera up, and remained silent until I was filming. I shooshed him pretty quickly, but that's his voice you hear for a few seconds.

 

My Ears Hurt... Loud? Nah It's Not Loud... It's Defening!
And Yesterday I Was At An Iron Maiden Concert, Right By The Speakers And My Ears Didnt Hurt Half As Much As They Do Now... So It's Louder Than A Rock Concert.

Well It's Driven Under It's Own Power So That's A Good Sign, Just Got To Tidy Up Some Loos Ends Then It Be Reet!

 

Insignificant details things like wheel alignment and the likes I would assume...


Keep at it guys... and remember to wear earplugs next time.

I drove it forwards and backwards very slowly before - weve added more coolant and ps fluid... and the idle now seems pretty stable but its at 1500rpm. I have a mitsubishi colt and its at 1200rpm on that so its not that bad. My 1.6 was about 1100rpm idle.

The start up video is hilarious though. I'll get it uploaded asap.

 

Wow That is one heck of a job you have done there. I have been watching this thread for a long time now and i have to hand it to you.
