I'm pulling my hair out trying to dial in the injectors on my Radix LQ9. Does anyone have any data on these? Five-O has been useless on providing info on anything but flow rate. I've just realized these are just 8.1 injectors modified by Five-O. If anyone has a tune they'd like to share, I'd really appreciate it.

I have the black ops 60s and New Era Mike tuned it. Give him a call, im sure he can help.

 

If they are modified 8.1 injectors have you tried running the 8.1 settings? Minus the flow rate of course.

 

That's the next step. Just cross-referenced the part numbers today, so I haven't had a chance to get back tot he shop and plug those numbers in. I was just curious if anyone else has used these with success. Since figuring where the injectors came from, I've been reading up on other modified Five-O injectors, and an alarming number of people seem to abandon theirs for more common injectors with proven data after fighting them like I have.

 

I had their 60's/625cc (opened up Marine 8.1's) and I used most the Marine 8.1 settings. Do you have EFILive or HPTuners?

 

I'm using HPTuners. I wasn't really aware that there are different versions of the 8.1 injector. Though, I doubt the difference between the marine and truck injectors is significant enough to affect a tune the way I'm seeing.

I tried the stock 8.1values in my tune, and I'm still seeing some crazy pulsewidths. I'm talking 30-50ms - very rich. This one's got me going in circles.

 

Can you paste in screen shots of the tables you need help with?

 

Same here. I have the 8.1L Marine 65's from them. Used the stock 8.1 injector data and changed the flow rate
