Need Help With Base Tune

OZ Rally · Oct 6, 2009, 02:25 PM

Okay so I've been tunning my car for the past week and it feels like I haven't made any advances. I have the speedcorps mani, 16g turbo with ported 10.5 hs, ported stock o2 housing, 3" dp, 3" hfc, 3" catback, 440cc injectors, 12:1 fmu, walbro 255, bored fuel rail, stock evo intake, intercooler and piping.

This is the tune I currently have and leans out under boost.

Here is the most current log.

Any help for a good map to start me off with will be greatly appreciated. I can adjust the timing and such, I just need help with injector latencies and octane fuel maps.

Thanks

Why are you still using the fmu?

OZ Rally · Oct 6, 2009, 03:39 PM

I was also going to ask if I still need the fmu with those injectors and stock fpr?

the only thing i tune with is the tatrix cable. i still have my stock fpr as well

This is the tune I currently have and doesn't feel right at all.

i say first off lets smooth out both of your maps a little more. after taking a look they kinda loo all over the place in the higher load and rpm values. whats the car acting like?

and did you take out the fmu yet as well? that may have something to do with it acting wierd.

I'm currently reflashing my phone. I'll txt/call you in a little bit.

Were you WOT in either of those logs? The highest TPS% I'm seeing is around 45% or so. I'm not sure if there's no knock because you're not WOT or because the tune is very conservative.

OZ Rally · Oct 6, 2009, 06:41 PM

No I haven't done any WOT pulls because it ends up spiking to 15 psi. I'm just waiting for my wastegate spring to come in.

Updated first post.

I edited my fuel maps and smoothed them out a bit. But now I'm running lean under boost.
Some help please.

ThunderOZ · Oct 6, 2009, 10:05 PM

Let me know what happens on your end. My problem is pretty similar: 9psi, running lean under boost, fuel tables are maxed out. Currently using walbro 255, wrx 440cc injectors and stock fpr.

man u 2 have racked my mind tonite. smooth it out for it to work better and now lean? dang it!

as i mentioned to merc maybe some injector cleaner or seafom to clean out anything that mite be in there. and as i mentioned to john try some crc maf cleaner.

and both of your were running fmu's before the injector swaps correct?

man i need to sleep this one off and come back at it tmw!

Are you using the stock MAF?

This thread will help (last couple pages) Lean under boost!!
You need adjust your MAF scaling.
