The MS documentation seems to suggest that any more than 4 low-z injectors require the add-on flyback circuit - but I thought v3 incorporated that circuit already.
Anyone using v3 with no additional flyback - good/bad results?
Thanks,

MSII v3 flyback question
Yes - they are low Z injectors....will work with your std 2.5 setup.

Yes, flyback is integrated into MSII. I ran my MS-I with 6 low impedence injectors with no flyback board for quite some time. My Spider did not fair so well with 4 low impedence injectors. I fried 2 sets of output transistors. You will find with an ohm meter that the V6 injectors are about 3.2 ohms and the Spider injectors are 1.3ohms.
If you're not running MS-I don't worry about it. Measure the resistance across your injectors to make sure. You might be able to get by without. High inpedence barb type injectors are hard to come by and expensive compared to the o-ring type. You can make a new fuel rail easy enough. Some careful heating and bending of an extruded rail can mimic the stock rail. You will need a 13.5mm drill bit to make the o-ring seal. The bits are available from MSD for some ridiculous amount of money. $85 last time I checked. However that investment will allow for a wider range of injectors at reasonable prices.
