I'm coming up on the point in a FI build where I'm going to have to decide whether to use my factory ECU or replace it. And my HP Tuners cable isn't working now for some reason. Before I spend another 500 on a replacement cable (plus debate switching in a newer ECU than my '98 ECU), I have to consider purpose and options. Regardless of which way I wind up going, I'd like to see what the typical cost of switching over to an aftermarket EFI unit costs people. The main module cost is easy to see, but after harnesses, relays, replacing factory gauges, etc, etc, etc... What do you think you have into your system?

Thanks

What features do you need?

stock ecu to holley dominator efi on my car with lcd screen, transducers, boost solenoids, all harnesses etc I did it for about $3500 with a few hook ups. You will lose your stock cluster with the holley though. I was worried about it but got over it fast when I saw how much more you gain with the lcd screen

You could do a microsquirt for under $500, using your stock harness just modify it

Another 200.00 for the fuel/oil pressure sensors

Another 160.00 for Dakota Digtal boxes to get the factory tach/speedo working

Cannot remember where but I have seen the Holley HP for 1405$.

And megasquirt is 1200$ for a comparable unit that's ready to go and does not have a wife band included like Holley as well as some lacking features but has more inputs and outputs.

I'm going with Holley when I'm ready for the boost.

I'm around $1,500 getting deals on stuff and using a Dell Venue 8 Pro as a dash for Holley EFI.

However it saved me around $1,000 on buying larger injectors since low impedance are 1/3 the cost and I sold my old injectors so almost broke even.

Me here do you get those injectors for that price? That's the one item I have yet to lock in yet for parts I think. And not sure how much I need but 800 rwhp is the goal when stuff comes together.

Depends on if u want to control trans. Holley hp wont do it and u would need a trans box or go with a dominator setup witch would cost u more than the hp set up. I have 2500.00 in my holley hp with us shift ,boost controllers and 3 sensors.

LOTS of good info here, thanks for pitching in everyone. It's good to see costs of different systems, and what options you paid for.
