Maybe you could try different spark plug gaps and see if that helps.
I did a bit of reading regarding the blow out. It's actually from what I've read a rather rare phenomina, but a term used to describe what occurs when there is insufficient spark to bridge the gap and ignite the contents.

Its certainly possible given that the stock coils aren't what one considers the best.

poor fuel quality, insufficient fueling, high combustion temperatures, exhaust flow reversions from excessive cam overlap are some of the things that promote detonation or preignition or both... this requires timing to be retarded in order for the engine to not detonate/preignite... due to the fact these are under square engines, they need advanced timing to make good power due to high piston speeds, low TDC dewell time, and so if you can't advance timing, you're not making as much power as you potentially could
Regarding my build. The only stuff really left stock currently are injectors and fuel pump so pressure drop at high rpm is certainly possible.

Regarding timing Rick was adding 12-24 degress of advance with no effects. Still havent worked out why, all my time has been spent working out why the car doesnt run very well at present.

Looks to be an issue to do with the amount of charge in the battery affecting the spark. Battery is on charge, so shall see saturday. I sincerely hope that it is and that a soluton is easily found.

They didnt have ZFRs in the 7 range.

Have my parents car till they get back from Europe (28th of June). I hope to in this time:

- Get the paint fixed up
- Replace right hand CV
- Rewire the adpatronic so its not in such a silly place.
- Wire up the idle control to the adaptronic
- Get closed loop idle control working
- Replace Fuel Pump
- Replacing Knock Sensor
- Hooking up knock sensor to Adaptronic
- Get wideband interfacing with the adaptronic

Potentially:
- Wiring A/C up to the adaptronic so that it will idle up when turned on etc.
- Swap to Toyota COPs

And Way down the list:
- Wiring up Power Steering so that idle up occurrs

May as well at this point swap to a VE based map as opposed to the current system in place which means starting tune from scratch again basically. Should be able to reuse some of it? VE Tuning is all new to me, used to having multiple reference maps.

Also have to pay off new wheels and body part. Hopefully get plenty of OT to pay for it all....

Also heres the dyno chart that didnt work last time:

Bought some new rims for the car :


Unfortunatley suffered a casualty in that the passenger (drivers for you) is no longer with us, reversing into a pole has caused a crack to form in the headlight housing allowing rain in . Sad day, slightly expensive day as well. 240AUD for a new passengers side Sport20 HID (second hand):


Car has about -2 Degrees camber, even with the camber (granted its jacked up but still) the rims are proud of the gaurds:




Also fitted my fog deletes and installed my original SP20 headlights:

Suffered some bad luck recently.

First was the starter motor, replaced with a Denso 1.4kw 626 Starter, works much better (sort of more later). Stock Left vs Denso Right:



Then a Indian gentlemen whom didn't speak a word of english t-boned me:




Car was working perfectly at this point, no cv whine, no starting issues. Perfect. Got it back from the smash repairs and the plugs were ****ed. (Fouled to the point it wouldn't start). The exhaust ports had turned to sludge from the amount of fuel that had been injected and not ignited. Cat was full of fuel, after a week of not running it still smelt of fuel.

After I got the car back I noticed that the cables that go into the ECU were starting to get bent from people stepping on them. As such with the help of a friend relocated the ECU and attempted to solder the knock sensor and crank into the ECU in an attempt to get the Air Con, idle air control valve (its winter here so it's taking a while for the engine to warm up sufficiently that it will idle itself) and tacho working.

In short the crank and cam didn't work, so they've since been removed again temporarily. And the USB port in the ECU was broken off at some point. I can't praise Adaptronic enough in that I express posted the ECU on wednesday and got it back the following Monday. In that time they replaced the ECU port and then sent it back express post. Thoroughly helpful. They even sent it expressed post back to me

At this point the engine stopped running. Leaving me and a few friends stranded in fasta pasta car park. Fun, not.

Since then I've had new tyres put on the rims, have had to raise it by 25mm rear and 15mm front. Mat also flared and rolled my rear guards a heap. Did a epic job too IMO

To get it all to fit having to run 4 degrees camber in the front and 3 in the rear. (Would like to dial this back to 3 per corner tbh). Hopefully that plus dialling in a lot more dampening will prevent scrubbage:




Front:


(Above shots pre camber)

Im going to need to get some new rims though, running too much camber for my liking to get them to fit really. Ill use them till the tyres wears out while I work out what I want to do.

Problems/Things left to do to get it running:
- Engine doesn't turn over. Before it went on jack stands it worked flawlessly so unsure what the issue is here. Relay seems to be working fine and battery has plenty of charge (its been on charge).

- Work out wtf it wasn't running in the first place. Could be solder join related potentially. Anyone know if the stock ECU needs to be earthed? (i.e. does the stock brackets earth the case and thus the ecu?)

- Bolt everything up tight suspension wise and double check all suspension is the same height.

- Swap back to 2.5" exhaust or rotate the stock mid pipe 180 degrees as the shifter linkage is currently hitting it. (Swapped to stock exhaust as originally thought the cat in my 2.5" was shagged).

Parts list I have for the car to install:
- Autoexe/Mazdaspeed Rear Wing
- Ford Laser Ajustable Wipers
- New Front Left Guard (Premium Beige Coloured :P)
- Swap blacked out lens into new HID headlamp.
- Install Mazdaspeed Familia front sway bar
- Toyota Coil On Plug Conversion.
