Just bought this.
Megasquirt I
- PNP Harness (needs one lead resolderd)
- 90 Degree Serial Swivel Cable
- Serial to USB Converter Cable
- Aluminum Mounting Plate (fits in 1.6L OEM ECU Location; bolt-in)
- GM AIT Sensor & Wire
- OEM TPS & Wells VTPS (needs to be retrofitted)
- 460cc RX7 PNP Injectiors (injector doctor cleaned tested)

Now, i plan on removing my afm. Do i need to purchase anmore components?
Also do i NEED a VTPS, can i use my orig one? How hard would it be to retrofit my wells VTPS.
Also, for my 200whp goal, would i need a 190lph or 255 lph fuel pimp?
I have a 93 eunos roadster m/t, 1.6 that has a custom Vmount, and t25 turbo.

 

get little connectors for the IAT sensor into the MAF harness.
VTPS is not required. I don't have it and the car is tuned well enough that I don't think VTPS will make any noticable difference.
I'd buy the 255 pump if you're going to spend the money.

 

sell your 460 injectors and buy my 550cc

 

couldnt i de-solder a old afm and remove the "male" plug from the afm and make a "jumper harness"?

 

Yep. I like to take 30-seconds to crimp and continue winning at life though.

 

Can i use my freinds tuning wideband? Or do i have to have one actually hardwired? His just has two alligator clips and a cable with a guage, just to have in the cabin while tuning...

 

190lph, unless you want to run a afpr. Read the FAQ sticky for why.

WBO2 is SO over-rated. Don't bother.

j/k. YES, you need a wideband. Your MS1 can tune to afr targets. You can datalog to tune, etc etc.

 

when you do to AFM removal you need to jumper the fuel pump.

I added a switch to turn the pump off when im messing with the ecu with the engine off.
Its a nice little touch. you can put it in your center console near the trunk release for stealthiness.

 

Get a wideband.. Take a look at 14point7.com for a cheaper wideband.
The guy is local to the GTA.

 

On-board wideband is the best diagnostic tool you'll ever have.
