With ez117k you'll need some way to give it a load signal/pulse. There also exists ez118k in europe which is a standalone ez117k. It uses a manifold pressure line for the load and I assume the distributor hall. you will need to reflash the chip to limit the advance though with any of the ezk

edit: heres a cheap one https://www.ebay.com/itm/233986365369

At that point I'd get a used microsquirt to control spark only and run some carbs. The Aliexpress DCOE knockoffs that KL Racing sells seem to work well from what I gather.

Also, let me know whether you end up wanting some hotter cams.

This is interesting, I didn't even consider that. I have an old CIS-injection 'knock-box' from an early Mk2 Golf that seems pretty similar in that it only controlled ignition and had a knock sensor, etc. I could probably retrofit it pretty easily since it only needs a MAP signal too. The downside is there's no information about remapping, vs the Volvo EZK which might be possible. Hmm.

Given that DIYAutotune's black friday sale started today, I may just go this way.

Hotter cams? The ones I have are the PZ penta cams, which are still essentially stock stuff...but I'm curious now. What grinds are you referring to?

I have some old RSI blanks, and some regrinds (currently in the car)...11.2 mm lift, 276 degrees.

I have a ezk 118 left over from my car if you want it, the hall setup is pretty simple, I still have a few back of head distributors with those too. It's a basic rotating 4 hole disk, so you could probably move the sensor.

The bits I still have
https://www.marktplaats.nl/plaats/m1...4409741512b6e6

I once read somewhere that if you plug in the block mounted distributor with the hall on this it should also just work. Maybe you could hybrid something with this and the buchka wasted spark, it should still have the same connections inside (5v+, gnd, VR conditioner and ignitor wire) as it also uses the same ignition modules. That would also give you space by mounting the ignition coil elsewhere.

As for the chipping I could take a look inside for you, Cameron (redblockpowered) has been trying silly stuff like using the ezk from a 480 turbo, and the ezk116 bin simply just worked on those

Took a quick look, completely different inside. The processor is a 8041 from intel and the dip28 is actually an ADC chip, so presumably the mapping is set by some resistor combination or just burned in somehow. Hayes says this should be 15deg BTDC base timing for the b230k it came from, so it is quite a lot of advance already in comparison to other b230 engines.


Just realized that the buchka board assumes the flywheel 58-2 pattern, so that won't work either unless the code is altered

Now THAT looks familiar. It seems very similar to the VW knockbox ignition I was talking about. Dual PCB, ribbon cable, no clear 'chip', MAP sensor, etc. I'm going to try to dig it out and check the insides . Thanks!

Well I just dug out an MS2 I was using on the B6304S swap and have decided to just use that. I'm really looking at the cheapest way possible, and since I already have it...

I started assembling the front of the engine today. Swapped the IM shaft to one from a B21 I have on a stand, replaced the IM and crank seals, installed the timing gears, modified the penta front lower cover so I can have timing marks (it's not pretty because you have to cut away the mounting boss for the fresh/salt water pump that runs off the IM shaft, but it works), and started mocking up the brackets to see how it all fits. Going by the water pump pulley, it looks like the AQ171 harmonic balancer is already shaved for use with a B230 bottom end, because everything lines up perfectly so far. This is a nice surprise .

Bought a set of Saab 900 plug wires...and they sorta worked. #1 was too short, but I had a blue NGK redblock wire that sacrificed itself for the cause. I had to swap the cap ends over to some slimmer elbows to get everything to fit, but it's done now. I also found a non-rotted water pipe at the junkyard yesterday, on the ONLY redblock car they had. Cleaned it up, gave it a shot of red, and one less part needed for the swap. I have a power steering pump bracket coming, and if I could dig up a non-crappy alternator, I'd have everything I need.

Minor update: I de-modded the MS2 back to single coil/hall sender/distributor status and it all seems ready to go. I'll probably wire it into the car as-is to be ready for the swap in the future. It'll give me a way of testing my diy-shortened-LH2.2 dizzy. It's getting pretty cold out already (go Canada!), so I'm not sure when I'll get to it, but we'll see. The garage is insulated but not heated so it takes a while to warm the place up.

Got any more detail shots of that bottom timing belt cover?

Sure. The AQ171Cs came with aluminum bottom covers (most of the AQ engines do it seems) that the fresh water pump bolts to and works off the IM gear. With the AQ140A in my car now, I tried running the cover as is, but the fresh water pump boss fouled the belts. If you cut it off, it works fine. It'd be possible to weld new metal over the hole, but I don't have any problems leaving it open. Honestly, it looks like any other lower cover except for the extra-long standoffs, since it doesn't even come close to mating with the block when installed.

PARTS DELIVERY DAY!
The 16v DCOE manifold from KL Racing showed up today. Two weeks from Sweden to Canada...gotta love a global society. I just ordered a used B234F exhaust manifold on ebay from the USA, lets see how long it takes to arrive. Canada Post is peculiar.

Ah well, I didn't get much traction on my wanted post so I figured nobody had one, lol. I jumped the gun a bit on the manifold purchase on Ebay because I had just gotten back from a meeting with the accountant helping me sort our issues with the Canada Revenue Agency (the IRS of the North), and it was VERY positive...so I indulged in a bit of junkyard part buying, lol. Taxes suck, which I'm sure is a universal issue, so it was good to get positive news.
