Default EPS conversion

Sammy Valafar and his crew appear to have an EPS conversion for the NA/NB now. I don't know anything about it and we're not selling them. Just an FYI.

I think that setup could be the ticket for people with swapped engines (like an ls). A notched-depowered rack will fit an OTS dry sump pan as far as I know. And as shown by many, a track driven LS is usually just a time bomb without a dry sump. I'll personally be picking one up in the next year or so.

We have one on order to evaluate. It will go into my race car. Will report findings in a few months.

It would be cool if it could output the steering angle and the load for idle correction through CAN. I would do it in a heartbeat if it did.

That's what I am hoping for. If the system turns out to only function in dumb mode it'll still be nice. But if we can actually build some 2D maps, use VSS and steering angle, that would be sweet. Hello 5.5° caster on 245's.

Looks similar to what I built for the exocet last year. They just cut the column and use the front firewall mount floating and have that bearing support the shaft/assy. Mine for reference. It's about $150 in parts. For his crazy price I should start making them to sell. Replaced lower end and used the actual EPS shaft as the new lower, remove stock lower column bearing and add a 3/4x1 3/8 bearing, which is the EPS shaft dia. Saves a heap of money. PS is "dumb" because it runs in fail-safe mode but has good feedback. I have a prius module in mine. YRMV.

Worth noting they use Equinox/Vue EPS units which are overboosted compared to the toyota/kia units, however they do have a potentiometer built in (looks like they use an extension lead and **** - they're built on the board at the factory) so you can adjust the assist to what works for you. All of the sensors/motors are typically made by denso. The overall package is really nice - a lot nicer looking then mine is.

Shot of the 3/4" ID * 1 3/8 OD bearing in the miata shaft front housing (Ebay, $8). It bolts to the firewall just like the stock column and acts as a floating front support. Pictured on the 3/4" EPS shaft.





Like I said, about 150 in parts. I don't want to take away from the kit being offered because the fit and finish of theirs is very nice and admittedly much nicer then mine - but the price range will put it out of reach of some. You CAN do this yourself if you have access to a welder (person) or welder (device).

Edit: Here's the original article I used last year to dial in my gain. It talks about the potentiometers, the controllers, the signals, and how they interact. It may help some of you wanting to use megasquirts.
