Help with Megasquirt setup

Hi Guys,

I am after some help with getting my Megasquirt converted Silverstop Zebec running better. i am running MS1 on a 2.0 silver top Zebec running GSX-R 750 throttle bodies, i have connected everything up, it runs, idles lovely will rev when you give it throttle however when you go to give it half / gradual throttle it just goes all "fluffy" and bogs down like its getting to much fuel etc.

I have not got a clue how to use Megasuirt software etc to adjust thing but i was looking to get a decent "base" set up to allow me to drive to somewhere who could set it up properly on dyno etc.

Is there anyone located in South wales area that could assist / knows how to make adjustment to get a decent base value?

Cheers.

Have you got Tuner Studio on your laptop for a starting point?

Who put the Base map on to get it running?

I bought the car has an unfinished project of sorts, the car had been running on the road in its current setup for a number of years with this Megasquirt/ throttle body setup however the previous owner dismantled the car to make some changes and paint and never reassembled it so when I bought it I had to undertake all the unfinished jobs and essentially just plug all the engine sensors wires from Megasquirt back in to how they were before, the only thing that I have to physically wire in was the lambda sensor.

It fires up on the button, idles around 900rpm, revs if you give it a lump of throttle but bogs down if you give it gradual / partial throttle. The plugs were black when removed covered in soot and when I cleaned and gapped them it improved things.

I have downloaded ďTuner studio MS lite V3.0.28Ē on my laptop and I have the serial port lead to connect into the Megasquirt ECU but thatís where I stop as Iím not good with this kind of thing.

Have you put fresh fuel in?

Should really run exactly how it did before it was taken off the road tbf regarding the MS settings

Yes fresh fuel, and I agree I though if it was on the rod for a number of years it should be plug and play, maybe thereís something silly Iím missing however I have no spare plugs or wires for engine, everything is where it should be as far as I am concerned. Hence why I was hoping for someone who was local to me to take a look via Tuner studio when is running to see if something could be identified.

Maybe I should get it off the axle stands and take it down the street to see if itís any better under load, although canít imagine it would be

My first guess would be the throttle position sensor isnt working

Is there any way of verifying this other than via Tuner Studio?

Thanks

I have just realised why my Tuner Studio would not connect to the ECU on my car, I have never purchased the registration and entered it in th software I downloaded.

I have just done this now and it stated ďRegistration ActivatedĒ so fingers crossed when I connect later to the car it will work
