vududoc have you tried the injectors? I have been inquiring into them and was wondering how they actually performed?

From my research into these injectors i have learned the daughter board is basically a piggy back to the ecu. my.02

How hard is the bord to install? Do you have to solder anything? Does it moniter AFM signal and stuff to adjust or does it just lean it out at low RPM?

Couldn't you just use a SAFC to make up for larger injectors?

ok following up on a bunch of questions so this post will be all over the place.

No i havent they are new in box. if one is bad np in sending it back for replacement. I also get power enterprise ones and you can look at my site for some pricing and power for the pn. good read is on differences in injectors along with sray patterns. basically the 11 holes are for better fuel atomization.

the daughter board is more aggressive piggy back and i'll have to find out more. im sure its on the net the install till i find out the particulars on the install. difficulty is guaged buy whos doing it if you know what you're doing should be easy. my reccomendation if you dont take it in.

i have a picture of the daughter board and will post that.

SAFC can compensate...normally injectors and turbo is common where im at as upgrades so people opt for the ecu. ecus run just alittle more than the safc and are designed for your setup.

Bare with me as there are numerous parts i carry and have to have info on that i'll have to get back with specifics. please while this is occuring search the net.

SR ecu's can be chipped (reprogrammed). You have to desolder out the existing EPROM, solder a socket that you install the daughterboard in. Daughterboard has 2 EPROMS on which can hold up to 4 different maps. You can have a stock map, a valet map (won't rev past 3K), a Z32 MAFS with 50lb injectors, and any other customized map. I got mine from BadBiki, an Australian tuner who designed and sells these. You can get the ROM Editir online for free and then use a EPROM programmer to program the EPROMS if you're brave enough to mess with them.
