Haha I'd take any excuse to visit anyone at this stage

Well this old horse finally drank the water. I honestly wouldn't have known how hard the car was falling over if it wasn't for the dyno.

 

So yerp I turned the boost down as far as it would go, about 16psi, and retuned it using virtual dyno in conjunction with the PCMTec data logger, to help get a better looking graph.

 

Talk about time consuming! I had to learn some excel functions cos the data wasn't in a friendly format but after sorting that, I think I made some solid tune gains. Thank fark for partial writes with PCMTec!

 

Here's a pic of the previous high boost (in green), first low boost pull this morning in blue and what I ended up with this arvo in red.

 

The blue and red are both on the same boost level (16psi give it take), green had roughly 8 pounds more but much less timing.

 

I used 6 smoothing to closer reflect the actual dyno numbers I saw the other day. Either way as long as I stick with the same settings I can measure the changes.

 

I think it's fair to say the exhaust is the issue but I'll see what happens with new genuine coils and plugs.

My mate had his Mazda 3 virtual tuned. These were the increments each tune was going up by. Very small duty cycle changes.

Haha yeah partial write for the win!

Whatever you do you need as much Data as possible for anything you do

 

Start runs as low as you can, log well before and after, load the vehicle up in all aspects.
 

Get aftermarket Knock detection !  
 

kick arse and chew bubblegum

I've got tuner nerd w/ dual sensors (installed) but haven't used it much. I will pull my finger out and do more checking tomorrow.

 

I reckon I can up the wgdc earlier before it falls over and then let it ramp down again.

 

Have got the go ahead from the finance minister to buy more workshop tools for exhaust fabricating so that'll happen soon enough.

 

Thanks for the support

I'm thinking of doing something similar and hooking up the USB data acquisition board I've installed for logging the wideband on PCMTEC.

Have you got the knock detection hooked up for data logging?

[Puffwagon]

I've already hooked up the dlp8 with the wideband but not the knock sensors.

 

That'll be tomorrow's job along with swapping plugs cos they arrived today.

 

I'm not sure that I'll get the tuner nerd box working properly with the logger but I'll give it a crack.

 

Today was a wash as I had my 3yo daughter home.

 

I'm down to half a tank now and I've got 40 litres of E85 here, so I'll top it up and give it a sprinkle of timing.

Yeah looks like you can log the DLP8 channels with PCMTEC, but also might be some maths to get it to output something useful. Would be worth it though so that if you hear something you can see exactly what was going on afterwards.
