Bonzo's progress

Personally, I am torn between the Two

I have the patience to mess about with wiring but I do like the smell of resin & enjoy working with the stuff

Must have a kinky streak there somewhere

Not too much progress with the build since midweek, been a little tied up doing other things.

That said, I went out to the workshop for a tidy up & took the fancy of having a crack at wiring the engine up .... Yep, that's me .... Working in an entirely random manner.
This is probably not the best way of doing things but it make me feel good & at least it contributes towards crossing another job from the list

Some of you may have read in the electrics section of the forum, I ran into a wee bit of a problem !!??
This is a continuation of that thread really but being as it is some progress, I thought I would post my result's here

Thinking that I would get right back to basics, I sat down the other evening & went through the ECU & Engine management diagrams.

Took a spare EEC IV plug & labeled all of the tails .... Here's a picture of the end product.



The tag's have all been checked, then double checked & thanks to Enoch, I was able to check once more from a chart that he kindly sent me

To be honest, when you sit down & really study the engines wiring diagrams, it is really quite straightforward ( That's going to come back & bite me !! )

My plan is to make up a custom engine loom to suit .... Just a personal preference really, that way I will have a loom that is tidy & will fit, where I want it to fit.
I guess it will also save the effort of trying to bundle up those extra feet of cable out of the way.

Next job is to do a little research into what sensor wires coming from the ECU I will not need.

A few spring to mind as possible definates .... Air conditioning wires, Power steering pressure switch, canister purge solenoid

A couple of not sure's .... Gearbox speed sensor ? & Inertia cut off switch ?

That's where I am at the moment, i'll not be working on the build for the next week, sadly I have other things that need to be done.

Keep you all posted folks.

Some of the sensors may not be needed from your point of view, but it is possible that the ecu won't like being disconnected from them. I really don't know if that would happen in your case, but it might be worth allowing for if you can't get any hard info on it.

In the case of the inertia switch, I would imagine that the ecu would want that, although you could delete if you know which way round it is and join the correct wires (IOW if the switch is normally on (my guess) or normally off)

[twinturbo]

The inertia switch usualy sits in line with the fuel pump feed to cut the pump in the event of a heavy impact or rollover.

Omiting some of he other things ( CANP ) will most likly throw a ECU error, however they will probably not affect the running. We have many sierra members running 24V Granada engines with both the Emissions gear and Autobox actuators removed. In some cases measuring the initial resistance of the Sensor or actuator and replacing it with a normal fixed resistor has worked in some instances.

A very valid point indeed Mr H

The " Will the ECU be looking for a signal ? " has crossed my mind & as such, I need to keep an open mind on this particular subject.
Yes, I will make sure that I do as much research as possible

Rob

A fixed value resistor has also crossed my mind .... I guess the trick there is finding the value the ECU is looking for.
Again, plenty of reading to do as yet

To be honest chaps, I am only going this route for the challenge & in the hope that I manage to learn something in the process .... Hopefully i'll learn more than just " should have left the wiring alone "

[big_wasa]

The canister purge does throw a code but as said doesnt stop it running and running well.

Ive got three codes on mine, all for the emmision's crap that went in the bin.

The speed sensor, I havnt used it on mine yet but may retro fit it when ive done a bit more testing. Its meant to do things like like cut the fuel on over run ect.

No time for my build since last week .... Working my way through a list of other things that needed doing

Last Saturday was a nice little trip up to Exeter show, had a grand day out indeed

Knowing I needed the workshop to make a start on the MOT work on my Jeep Monday, I had a very quick tidy up on Sunday & made a start on an aux fuel tank I had been asked to fabricate for a motor X bike

Here's the completed tank.



Not the nicest thing I have ever produced but I had a very tough brief for this little job .... Must cost very little ( Cheap ) & use whatever materials I had kicking about.

I would have loved to make it in alloy to replicate the pattern given to me .... Unfortunately, out of the budget range for this particular jobby.
Guess it didn't turn out too bad in view of the limited materials available !!??

Jeep went through it's re-test this morning so that's that job out of the way until next year.

This afternoon saw my eldest's tatty Escort van enter the workshop for MOT work, I ain't kidding, it's a minger !!
Told him last year that was the last MOT for it but here we are once again !!??
All of my favourite jobs to do ( NOT ) Spring hangers to weld, lower wishbone & CV boot to change .... Rest of the job's are quickies.

That will definately be the last MOT job I do until next autumn.

As per title, counting the days down so as I can get back to work on the Roadster .... I have a strong urge to get the engine up & running real soon

[Bonzo]

Firstly, I can't believe that it has been over 8 months since I last made any real progress with my build !!??

Last weekend saw the arrival of our 4th Grandchild .... A healthy little girl named Chloe

Being as the wife is now clucky clucky I have taken full advantage of the situation & in true Bonzo style, I have ditched work on the kitchen n hidden myself away in the workshop .... Well, we can't have that little one breathing in all of that nasty dust & things can we ?

Now to the point of this post.

All change on the engine front, out with the Zetec & in with the Vauxhall C20XE Redtop engine.

Here's a couple of progress pictures.







The engine is now more or less where I want it to be but I have a few niggles to overcome !!??

Front of the engine is a tad too high for the GRP bonnet

Not much room for the air intake using the stock inlet manifold.

Fuel pressure regulator is going to get in the way, no big deal as I can bypass that & fit my aftermarket fuel regulator unit.

I had given some thought into lowering the engine a little more but the Omegas bell housing is already 30mm below the chassis rails & after reading Rob's recent thread, lowering the engine further might not be a good idea !!

I have a fair bit of room to move the engine further over towards the passenger side, the crankshaft more or less follows the centre line of the chassis at the moment.
If I move the engine off centre, how will this affect the dynamics of the car ??
It would certainly give me more room to fit the air intake.

Don't know if anyone has any thoughts on the subject of engine alignment.

Hope to get a little more done over the weekend.

First uj on the prop will allow for any "misalignment" of the crank in any direction
oh and nice to see you back to PROPER work go Ronnie go go go
