Does anyone know the flow rate of the EA TB injectors. I know they are 100kPa pressure (all TBI's are low pressure). I think they are around 80lb/hr but not entirely sure. Adrian, not sure on flow... will have a dig through my C: as there's all sorts of random EFI stuff kicking around on there... High possibility of these being low imped injectors, yes?

These are low inpedence injectors. 1.4 Ohms I think.

Im fairly confident the V8 has the "grey" TFI module (non-CCD) as it's straightforward mustang gear... the 6cyl guys should look into this as well.
Martin The service manual doesn't differentiate the EL 6 vs all V8s, except for the number of vanes on the hall sensor. 6 and 8 respectively. They say the TFI module supplies the PIP signal to the ECU, which sends back the spark out (SPOUT). When this happens the TFI triggers the coil. The TFI also controls dwell. Sounds like it is a perfect candidate for MS. If EDIS gets to hard I might get a TFI dizzy and adapt it to the Cleveland. Because mine is a very late block (ZJ fairlane) I am pretty sure the only difference between it and a windsor one is the gear.

Well, got a base map for a supercharged 302 coming soon.... will download the Megatune software and have a play around with it...
Plenty of questions regarding install to come, lol. First up. was having a think about the injector banking on the HO.... if the firing order is (IIRC) 1-3-7-2-6-5-4-8... Wouldnt we set every 2nd cylinder to one bank and set MS to squirt from alternating banks... i.e. 1, 7, 6, 4 as bank 1 and 3, 2, 5, 8 as bank 2... so set to alternating and you get the order of 1,3,7,2,5,6,4,8... Also, can anyone tell me the pin numbers on a V8 eec for the injectors? Max Ellery seems to have omitted these... Thanks guys.

Alternating firing means one bank fires one rev, the next bank fires the next rev. A four stroke engine has 2 revs per cycle. There are 2 injections events per cycle (if thats how you set them up). You will also have 4 spark events per injection event. Therefore your have 4 cylinders firing on one rev and the other 4 firing the next rev. Thats why I would bank them in firing order. eg Bank 1 = 1,3,7,2 and bank 2 = 6,5,4,8. In the end the MS wont know which is on the firing stroke, because there is no cam position sensor, so you could bank em how ever you like. For loom cleanliness you'd probably have one engine bank per injector bank. Eg 1,2,3,4 on one bank and 5,6,7,8 on the other. If a set of cylinders get a squirt on their off spark stroke and the engine is cold the fuel might fall out and pool. You'd get a poor idle but it wouldn't last long. For consistant running, because of the above, it might be best to split firing order up like you suggest. There are many arguments to go many ways, but my V8 certainly doesn't swing both ways !!!!! I'd try many ways and see what works best. Tonight I will see how the 6s banks are aranged, that would be something to follow. I'll also get the V8 ECU pinout to you.

PS For me this is of no concern as initially I will be using TB injection on a single plane manifold. I will go multipoint at a later date (mostly determined by budget).

Brilliant - I appreciate your help there Adrian.
Lol, already got a ring binder full of MS stuff.... jus the basics 
Yeah id like to think my HO doesnt swing both ways... but ive suspected otherwise for some time now

The 6's are banked 1-3-5 and 2-4-6

Just as I thought. Injectors banked into firing order.

Cant it sense that from the PIP? #1 TDC is indicated by a (shorter?) tooth.

Compression or exhaust? Compression, as PIP comes from TFI/Dizzy, which rotates at 1/2 of crank speed

Of course!!!!
So, i note that our V8s have specs where the base timing is 30*BTDC +/- 2* All the literature ive been pouring over suggests the "normal" base timing for a TFI system is 10*BTDC, which i believe is true for the Aussie I6. Unfortunately i no longer have a timing light to sus this myself, but... Does anyone know if 30* is the actual base timing for the Aussie HO? (i.e. did ford Australia physically advance the dizzy an extra 20* from the US specs)... or if its simply a "trick" in EEC's timing maps?
