Default Eficonnection how do you like it

I am thinking about going to a eficonnection set up on my 1997 TA. I am tired of opti problems and now my harness seems to have a short that I can not track down; the eficonnection will get rid of both my stock harness and opti. How do you guys that are running this system like it?

EFI Connection = company name
24x System = LS1 PCM conversion

The EFI Connection 24x LS1 PCM setup is THE single best improvement for the LT1 engine in my opinion. A must for guys like us that stick with the LT1

Agreed, having a 93 of all years it was well worth the money in my case. Being able to tune the car with Hptuners and not having to mess with burning chips, not having to mess with speedo calibration boxes or speedo gears to correct for different gear ratios have all made it worth while for me. It's nuts how popular the system is, not on the internet but in real life, I know of at least 3 cars including my self running it in the Houston area alone.

What are your plans for the car?

I have the 24X system and EFI Live.

If you want a badass engine management system without jumping to FAST, BS3, etc. Do lsx ignition + EFI Live.

EFI is more expensive, but more capable than HP.

They both work well though.

I really could stay with the stock ignition, but I just can not get my system to work correctly for long periods of time. My car is only a mild 355 build with le1 heads and lt4 hot cam; it should be fine with factory ignition. So what should I do switch over or spend more cash and time to get my factory ignition working correctly; only thing stopping me from going with the efi connection set up is the price and 12 week delay for the harness.
