rough tables
Can you show me your tables for referance. Idealy something a little conservative to get me started. I have 1.8bp. Td04 turbo rx8 injectors an a small intercooler. Running MS2 Looking for a few tables to get me started or at least to check I haven't made any major errors. Starts and runs well. Stutters badly when I hit boost about 0.4 bar. Eventually breaks through and powers on.

Well in absence of a response I'll post my msq up for now. If someone could give my tables a sanity check and also my AE settings and slap me if necessary. I want safe conservative tables for now. I'm also running extremely low boost (0.3bar) for now because I'm still working out how to get some cool air through my cooler.
I now suspect the stuttering is related to fuel surging back away from the pickup (even though I have a small surge tank just before the high pressure pump) because it only does it when accelerating hard. If I hold the car back with the brakes under full power it doesn't do it.
No my other problem is the acceleration enrichment - it can't seem to prevent it leaning out for a half second when I put my foot down even with quite aggressive (I thought) AE setting. Or maybe I'm just being a 'tard as normal and missing something obvious.

Just looking quickly.
Your AFR table looks funny but should be okay.
Surge tank? Dafug? What was wrong with the stock setup?
Your VE table looks like dick.
Turn on autotune and drive. Easy. Drive smooth and easy for a while burning and saving a lot. Gradually raise boost. IMHO run open wastegate at first.
Your timing table is the most conservative thing i've ever seen.
Maybe someone else can chime in. 380cc RX8 injectors are a thing?
Did you set and verify timing? Trigger wizard is at 0*

Ah well when I say surge tank remember its a kit/homebuilt car so very little stock stuff remains. Actually the stock setup is pretty good but doesn't fit in my car. Tank is 27 litres and I KNOW it has surge problems but thought a small surge tank would correct - I'm still unsure if thats the cause.
RX8 yellow injectors are said to be 420cc and good upgrade for not too crazy projects.
I did run it round for a while on autotune and that was the ve table it produced.
And yes i set timing
I picked the most conservative timing I could find online so was probably overly careful - care to share your own?

While i can't comment on the surge tank / fuel issue, i do have issues with this:
Timing isn't your issue, here is mine still very conservative for reference.

If you mean the fact my timing is zero its because I turned the cam sensor until the light showed zero with zero fixed advance on the MS
If its with me calling the injectors 420cc and not 380cc I've only just noticed this an I'm going to look into it now! I can't remember what the seller told me they were and I have even less idea if its true. They are yellow rx8 for sure.
And thanks for the timing map if anything gives me an idea where to aim for

No problem. Really, i'm probably one of the last people to ask for help on this site. I know just enough to get me into trouble and that's about it.
