Holy crap! Most people would've just bought a chunk of aluminium stock, but serious kudos to you for recycling!

 

So what's the distributor trigger for? Obviously not accurate enough to use as a crank angle sensor...

Im guessing its a trigger to let the ECU know when the crank is coming around for number 1 to fire.

Yes the distributor is for cam sensor, the crank sensor is still on the to-do list

You are a mad-man.

Love this!

Making some more aluminium parts, had to weld this one together - I have carefully hidden most of the ugly welding from this photo but it's structurally sound at least.


Found the necessary 7mm machine screws hiding inside some old head bolts.


Add some threaded spacers and you get this.


Which will eventually fit here.

Ahh - are you going individual coil packs for ECU reasons? Clever stuff as usual.

[76lxhatch]

It's kind of the other way around, I'm going to have to change the ECU because I want to go to sequential injection and multiple coils with electronic throttle... just the usual snowball effect

[SmacT]

Yes, sorry, that's what I meant. Which ECU? I have a Haltech Nexus R3 in my sights one day, got a Platinum Sport for now as it came with the engine.

At this stage I'm thinking a Link G4X XtremeX, plan is to figure out the crank sensor and pedal then move on to the big ticket items. Will probably end up doing some re-wiring to go with it

[SmacT]

Nice! Adding some sensors too? All that stuff is getting easier and easier.

[76lxhatch]

The Delco has been great and has a lot of factory features, I really hope an aftermarket offering won't be lacking in comparison. The batch fire injection in particular has its limits though.

 

The idea is that sequential injection will offer timing control that will help with low rpm driveability when dealing with cam overlap, and more options for fuel trim (might run an oxygen sensor for each bank). Multi-coil will eliminate the mechanical distributor to hopefully make it run a touch smoother and avoid the associated wear (the MSD stuff seems to be quite hard on rotors etc). Both of these require cam and crank sensor, since it will be clean-sheet I've decided on a reluctor with 36-2 tooth crank trigger along with the hall effect cam trigger.

 

Changing to drive-by-wire throttle eliminates the IAC and gives more control over progression, I'm at the limit within the physical constraints for the current cable setup. The manifold air temp sensor will be relocated into the air cleaner as intake air temp which might be helpful with the cold air intake. Everything else in the engine control department will pretty much remain as-is, still MAP based.

 

It would be nice to update some of the standard wiring while I'm at it, the gauges always read differently with lights on and I've had issues with voltage drops in the past. Would also be an opportunity to update the fuse panel with additional provisions, but we'll see how far it gets.

[SmacT]

Ha ha - I think we both know how far it will get! Once you start on that path... Can't wait to see it take shape.

[76lxhatch]

As with so many things on cars, the coil brackets needed to be done twice (one for each side). Got the remaining hardware turned and stitched together the second bracket, then fixed the colour.

 

Much better, doesn't stand out as much.

 

Since the air cleaner base will need re-doing anyway, it shouldn't hurt to add a half inch spacer for some added insulation. Ordered an open spacer, apparently there are none in the country... luckily its easier to make an open spacer out of the four-hole variant than the other way around.

 

I had wondered if the 82mm throttle body was going to be slightly on the small side given the massive sizes people are going for these days, but I don't think it will be an issue.

I want to follow this thread so much.......but I still can't see the pictures. It doesn't happen anywhere else on the site. Is it happening to anyone else?  If I click on the jpg file name it just takes me to a page that "can't be reached".

This happens for me on the work computers. Not at home or on my phone. 

[yel327]

Try a different Web browser.

[Shiney005]

Phone isn't an option for me. Too dumb.

[Shiney005]

I just tried it on Bing, but no difference. Everything else works fine with Chrome.

[yel327]

I have found on this forum that I can’t use it on Chrome or Safari, well I can but have to login every time. Photos work on Safari. It works the way it is supposed to on Edge. This is with W10 or W11, have PC’s with both. Safari is just on my iPhone, haven’t tried with the Android Galaxy tablet - it only gets used to talk to the Ram’s ECU.

[Rockoz]

I had a lot of issues with pics and log ins for a while with Chrome.

But after a couple of updates, it has all come good again.

Can you show a screenshot or post any more details/error of the page that can't be reached? As far as I can see there is nothing wrong on the server end but I do have scope to make changes, just need something to troubleshoot.

[Shiney005]

Sorry for the late reply. I've been away from the computer for a few days. Yours is the only page in here that doesn't work correctly for me.

So happy with the Holley HP EFI setup with so much adjustability. Screenshot of the hatch. I run mine in paired only because I don't have a crank or cam position sensor. Each cylinder has a fuel trim. Can run electronic pedals, early and late sensors, control and set PWM plus selectable input & output in both PWM earth - or 12v trigger with internal relays. Choice of three different tuning strategies, five ignition type inputs and the list goes on.

Thanks, I think I found a minor issue that could be the culprit - any chance it's working now?
