Junkyards here seem to be a great thing of the past.
H&S covid and "climate change" have ensured they are nearly all closed.
Never the less the Bosch valve looks just the job.
I guess if l blocked a few ports l could do away with all of the standard cold start/idle gubbins too?

Really interesting stuff.
I might look into that Bosch valve and try to find an ingenious way to feed it into the throttle body via the existing port.
Any ideas on this?
Thanks for the info.

Does anyone know if there is a throttle body (or attachment to) that will fit a 4age plenum and allow electronic idle control?

Once everything is working as it should fill the system with a really good brake fluid, l use Castrol SRF and it never gives any problems. Bleed the brakes before every track day. I use standard size grooved discs and Mintex M1166 pads on the front, 1144's on the back. Braking is good and fade free ...

What problems are you having with the standard brakes?

I would suspect ecu ignition drivers.
They were not designed to drive this type of coil.

Whilst l know (or thought l knew) what igf does l wondered if anyone knows what it actually monitors as a return to the ecu? I'm chasing a 0° btdc timing issue on a Freedom ecu and when this happens the engine will not start. The display shows 0° btdc in the ign timing log. I did nothing but cleaned...

Thanks Jondee. Good call on the reference mark, used both for depth and tooth position. I know that the pin type can be fitted 180° out and the distributor will only just have enough adjustment to get the timing required. Been there, done that! Pressing the drive on makes sense, if it should come lo...

Has anyone ever removed the distributor drive cog on a SMALLPORT distributor?
There is no pin to remove...

Toluene
We were doing this a long time ago.
Once you get past the crap on the linked page the information is good.

disconnect the plug at the ECU and disconnect the plugs at the injectors turn the meter on tone connect one side to wire harness 10 and then prob the injector plugs one at the time see when you have tone if they are connected in the harness you will get tone 4 times (one on each plug) good luck Sor...

Cam timing adjustments to suit the type of competition and with a twin cam engine this can be quite effective. Raise fuel rail pressure using internal pipe restriction (to help engine cooling if you are closing the exhaust valve early as above) The best low down power l ever got was by doing a compr...

I agree about the different fuelling strategies. l just needed to know about the wiring so that l could allow for it in my calibration.
Hasn't helped much though, just added to the confusion!
AEM tooth control tables are a law unto themselves.

I would guess they would fire in sequence, two outputs to halve the load on them?
My motivation comes and goes these days too, when l need some... l try a different ecu!

A simple continuity test reveals that on a U.K (map) car #10 and #20 injection outputs are linked in the loom, one trigger from either output fires all four injectors at the same time.

The Freedom ECU should be able to drive the injectors separately. A little wire work and a few keystrokes and you're in business. That is assuming you're using the programmable ECU. Group firing with the Freedom should be relatively easy then 8-) What l'm trying to ascertain is if the injector outp...

That's quite interesting about the outputs being linked in the ecu, l have just checked a Freedom ecu (l don't have a standard ecu) and the outputs are not linked internally. If the linking is done in the loom as the diagram suggests, would it just be case of doing a continuity test between the inje...

I'm still using the standard wiring loom in my car and l'm once again trying a different ecu.
From the Toyota workshop manual wiring diagram it looks as if all 4 injectors are wired to fire together even though there are two injector outputs labelled for different cylinders.
Can anyone confirm this?

Well, you make a very good argument for keeping the distributor! It seems a bit archaic but mine has always worked reliably and efficiently, as stated it is sequential too. This might just be a case of 'just because you can, doesn't really mean you should' Best l find someone who sells distributor c...

Great thank you Jondee.
On a 4 cylinder engine the distributor sensors represent cylinder 1 and 4 l guess.
This might be easier to go wasted spark with a coil pack as opposed to coil on plug.

After some experimentation it seems the direct igt output from the ecu will drive internal igniter type coil on plug coils. The issue of course is that there is just the one igt output. My ecu has the facility to output igd (the same as a 4agze DLI) and the engine will run with coil on plug in waste...

Sounds like a plan. Slightly odd with TRD stuff, l also have some TRD top mounts and there is nothing to distinguish them from standard other than the packaging. The engine mounts are definitely stiffer, l'll try what you suggest and if l find out anything regarding identifying them from part number...

I have a selection of AE86 engine mounts and two of them are TRD ones.
The problem?
All of the mounts are mixed up!
Anyone know how to tell the TRD mounts from standard?

Check to see how much comes out of the engine breather when you rev it to approx 4k in neutral. I would have fitted new rings and honed the bores (as a minimum) before installing the pistons. Can we assume that this blue smoke comes from the exhaust? Greta will pop by and spank your arse for driving...

That is an interesting article, the Honda system pre-dates Ford by more than 10 Years. Lexus used, l assume, a fbw steering system on the first GS450h It was designed to limit input correction when correcting oversteer, presumably they were mitigating an instant torque increase from the electric mot...

Yes JD it was a single adjuster type. l had a chat with the owner of the car and he is using the manual adjuster from the manufacturer in the link above. The positive to the conversion is the facility to use a 2.5 turn rack without added weight. Personally l think that the factory power steering is ...

So today l got to try a Vauxhall Corsa electric steering column converted to an AE86 with a quick rack. This system included an adjustable weight control. Whilst l remain very impressed with the lack of kick back through the steering wheel it really didn't matter where the weight control was set the...

This Ford oil.
Is it deep red by any chance?

Having just spent two Years testing and developing autonomous cars l can safely say that the starting point with steering is far from ideal! Getting back to "ultimate" steering l would be looking at a gts manual rack, power steering arms with corrected bumpsteer and reduced caster. I might...

Most modern cars with stability control use electric P/S and have an angle sensor built into the column. Apparently the E12 Corolla needs an ecu re-set if new steering parts are fitted. My E12 steering went into error mode and switched off after the front end slid on a wet cattle grid. l got away wi...
