i have mspnp2 in a 95 1.8.
I just changed to 515cc injectors and 255 walboro from stock.

i have been using autotune/Analyze Live! to help but anywhere from under 4k rpm, if i accelerate and try to go into boost, or just shifting into 2nd with just alittle acceleration, the car with buck really hard.

itll only happen 2/3 times but happens every time you try to get into boost under 4k.




i uploaded a log of just driving and accelerating lightly

 

Mostly, I'm seeing a bit too much acceleration enrichment - which is not something VE Analyse Live will touch.

Also, can you post the full MSQ too?

 

here is the full tune.

and i was wrong about it bogging under 4k. its actually under 3k rpm with less than an inch on the throttle. but once it is passed that. its okay!

and i checked Fuel pressure and its 40-60 right at the pump

 

The MSQ definitely looks like you have too much AE. Also, why are you using a secondary fuel load table?

 

I lowered my AE too 1000 and it stopped bogging under acceleration, but I didn't know I had a secondary fuel table...

Is that messing with anything or would cause unexpected circumstances?

 

It's going to make your primary VE table look rather weird.
