hello? can anyone help me jesus,

i'll go over this again.

I have spark
I have fuel
I have all the adjustment's correct
I've tried to change the CAS
I have timed the car
When the car is timed at 10 degree's it wont rev up past 1,500 RPM, basically it ascts way out of time...... When trying to rev the car you can hear the pressure comming back through the turbo because it has no where to go, once again like the timing is incorrect.
The only way the car is driveable at all is if the timing is advanced 20-25 degree's, when it is advanced the car drives like a normal car other than a bucking or bogging issue between 3,000 and 4,000 RPM.
I dont drive the car due to the fact that 25 degree's of timing advance from the correct timing doesn't sounds safe to me.

Does anyone know what my problem may be?
Is something incorrect in the MSPNP for it to do this?

Thank you.

Joey.


My Setup:
450cc injectors with resistor pack
GT28RS turbo
Godspeed front mount
MSPNP 90-93
HKS BOV
Deleted AFM
LC-1 wideband
Built Engine from FM

I think you pissed me off in another thread so I've been ignoring you. (but I can't remember and now that I think about it I think it was someone with a username similar to yours, whoops.)

When you set your base timing, are you jumpering the thing in the diagnostic box that you're supposed to jumper? Then when it's set your removing said jumper?

lol, i havent said anything crude to anyone, so doubt it was me

but im using the megasquirt to simulate the jumper, like the manual tells you to.

I still used the jumper on mine and my timing is accurate also try reflashing the firmware with a brand new msq fixed mine

Did you do anything else to the car when you installed the MS??

is your dumb *** setting the timing at a fixed 10 degrees? that would be awesome.

this is what you should have done:

1. set Fixed Angle to 10
2. adjust Trigger Angle value(or move your CAS) till your crank pulley shows 10 degrees
3. set Fixed Angle to -10

is that what you did?

yes that is what i did, thank you very much, but i just loaded someone elses MSQ. and took a look at it and the Trigger Angle Additon was at 0 and mine was at 22.5 so i said hell ill give it a try and it runs like stock....... why ?

Tonight im going to do the timing again with the Trigger Angle Additon at 0 and see what it does........

i also tried reflashing it and loading a new MSQ. and yes i unpluged the ignitor.....

don't just randomly change the additional triggle angle between 0 and 22.5. you need to set your timing to 10 while that is set. if you go and change it after setting timing it will be off by 22.5 degrees. that setting is used when you can't attain timing by just changing the triggle angle.

if you bring up the Spark gauge in MT does it fluctuate as you rev it up or is it fixed at 10?

if you set Fixed Angle to -10 the gauge should follow your spark map

its set to -10, i have said that before.

the gauge does follow the spark map.

and does your crank pulley show the correct timing?

yes, i had it timed witht he stock ECU and EMU and it works fine then i put the MSPNP on, timed it and did all the adjustment for my mods.... VTPS,Wideband,450cc injectors then all went to hell.

tried changing everything back to stock with the MSPNP and still no luck.
