Can someone take a look at these?

Had the car remapped and have done some logs to make sure Im getting the best from it....

Ive logged 003 and 020, 115 and 031, 118 and 032. 002 and 114.

I know a little about logging but if someone could take a look and tell me if they think the map could be improved or adjusted in any way.

From the logs boost is peaking at 1.5bar and dropping to 1.1bar, there is a strange dip in boost just around 5k RPM. Is this due to the high CF's?

Let me know

Cheers

overboosts, then can't make the boost further up? airflow is low, as you might expect - and the CF's are high.

weird. is the N75 standard?

Who's remap?

That's not CC, is it?

Timing is nothing special considering the CFs it's showing. As said, too lean for my liking.

You can see in 114 that the ecu is trying to correct the aggressive load.

(Good logs by the way :yes: )

Yeah, N75 is standard....could this be faulty?

When you say airflow do you mine the MAF is reading low?

Remap is by a local company in NI.

its a bit bloody lean is'nt it? 1.5bar boost and 0.93 lambda??? jeez...
did i read that right??

Dont really understand the lambda bit but if you say it is then Im sure it is.

Best to not drive it or drive it off boost?

There is no faults logged in the ECU...any parts I can check that might be causing this?

No not CC its a local companies map.

Cheers....I got what blocks to log from one of your posts;)

lambda x 14.7 = a/f ratio :1
MAF looks ok, I'd say the problem's the map itself.

Here's an old Revo log of mine...

Actual / Requested.
Code:
3360	0.953	0.938
3720	0.844	0.852
4160	0.821	0.836
4560	0.828	0.836
4880	0.836	0.836
5240	0.821	0.836
5560	0.821	0.836
5880	0.828	0.836
6160	0.821	0.836
6400	0.828	0.836
6640	0.828	0.836
6920	0.821	0.836
6280	0.797	0.836

As you can see, quite a bit richer than yours. *I know that some mappers like to map them a little lean as they come on boost.....

I wouldn't go off what I've said about your timing - unless someone else agrees......

Anyone offer anymore help?

Is it dangerously lean?....Bill would you want this changed if you seen it coming in?

Do you think the airflow should be more m0rk?

as everyone else has stated too lean and too much knock!

i'd get rid of that software sooner rather than later; it's even pulling out load at the top end, would be interesting to see the egt's i'd imagine they're rather high!

Could you explain block 114 to me?

How is the log showing you the ECU is trying to correct itself? What do the % mean in Spec. Load, Load Correction, Actual Load and N75 Duty Cycle?

Cheers
