Will fix that!

I'll fix the wiring to BAT >>STR >> ALT >> 12V

Miata has battery in the rear passenger corner of the vehicle, so I'm estimating I'll need about 12 feet of wire to get from the battery to starter.

Really appreciate all of the support!

OK,
So seems like I will have to do the wiring again from the scratch.

I'm using OEM Miata wires and they seem to be around 4 AWG and I do have a T in between battery/starter/alternator (alternator wiring is going through OEM miata fuse box)
alternator wire is around 8 AWG and starter wire is off ...

I got my battery replaced and the voltage drop during start up is same.
Since I cant move the main battery to the front, is it possible to run a small 12V secondary battery in the front?

Would running a secondary battery in the front help?

Thank you, I just connected the wire and the speedo is working.

I have 1 more question, what does the smoothing do?

Hi,
I have a k24 swapped Miata and I want to get my VSS working on my kpro.

I already found the VSS wire for the vehicle, it's a 5V alternating signal with 4000 pulses/mile.

Where am I suppose to connect this wire on the kpro?
Do I have to use the Digital Input wiring harness and feed the VSS to ...

Are you guys with problem running any VTC mods?
I've heard VTC limiter/pin can also cause erratic VTC angle readings.

I'm doing a k swap on a Miata using s2000 manifold since normal k series manifold ends up intake port on firewall side.

I have s2000 manifold with 70mm Tb.

What if I use b series 4 bar hondata map sensor?
Would ...

Thank you for the reply! So I shouldn't have problem using b series MAP sensor, right?

If I use B Series MAP sensor what parameter do I have to use in order to make this work?

Great timing that this thread came up. :)
So GM 13577429 can go in between the fuel filter and fuel rail, correct?

thank you very much for clearing this out!

alright thanks for the quick reply.

does hondata test ecu before they upgrade?
if I buy this, I was going to send it in to get it updated to v4.

Hi,
Is there a way to test hondata on a bench?
I'm thinking about buying hondata second hand from a guy but I was wondering if there is a way of testing the ECU off of the car.
I'm not close to finishing engine swap, so I can't test kpro in my vehicle.
