Re: brake options for daily fun car
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 ...

Re: COP
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...

Re: Distributor drive
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...

Re: Batch injection
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?

Re: Batch injection
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.

Re: Batch injection
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.

Batch injection
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?

Re: Igniter
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...
