DPJ's GTRS Eliminator Install and Development

[DPJ]

I was trying to get my head around Ignition Angles, CFs and Revo timing settings. I was comparing my 003 logs for HB9 at T9, T7 and T8. (As you know the T9 logs were showing high CFs and the T7 had CFs through lack of adaptation.)

I've been plotting the Ignition angles against each other. When I substituted trend lines for the plots, I got an interesting result, proving (I think) that my last night's T8 run has given me the best ignition advance the ecu has allowed so far....

 

[TBCupraT]

Was this using the same data from the log you posted last night?

The reason why I'm asking is that it says you got 7.5 degrees advance @4360rpm.

It doesn't appear to show in the graph.

 

[DPJ]

That's because I'm using trend lines rather than plots of the data.
Here are the three datasets.

T9 HB9 11 degrees outside. 50% wmi now.

I didn't get enough runs in before I had #2 coilpack failure. I don't know if it affected any runs before it let go.

Here's three runs, the middle one looks the best to me.

Comparing this to previous logs, ignition angle looks no better (maybe worse) than T8 up until about 5k rpm, then they look better.

Here's the trend line added for the middle run (in red).

Remember max wmi flow is being achieved a bit less than 4k rpm. After that, the flow rate remains equal, so the % methanol to petrol is decreasing as the revs continue to rise.

I'd welcome any opinions, I haven't formed any conclusions yet.

Block 114 from tonight. T9 HB9 50%wmi

 

[The MoffMeister]

good luck with it dave this means bugger all to me haha

 

[TBCupraT]

Yeah same here.

Looks like Tron with a belly full of stella.

 

[PhilW]

That turbo is hardly trying!!!

Looks good tho dave, whats 020 and i think 003 (BTDC?) like now with adaption etc...?

T9 HB9 50% wmi I was getting low CFs. I turned the pump pressure up from 150 psi to 180psi and the CFs are back. I'm going to run it on the rollers today with it turned back down.

 

[PhilW]

Your running it on the rollers today?

Where? Keep us posted with the results.

 

[DPJ]

Vsport at Boldon (new one on me.) Dyno Dynamics rollers. There have have been some good things said on Pistonheads. Going with 6 of our Ibiza members. I'll post back this afternoon as I'm popping out of work really.

 

[DPJ]

I'll post without too much comment. Good setup at Vsport and likeable, knowledgable lads. I'll almost certainly go back. Whether there was enough load on my car, whether the setup's wrong on the wmi, I don't know...... dyno lottery.

(I told them it was ok to run it to the limiter).

I'll post my last JBS graph (without wmi), then the Vsport one (with wmi)

I queried and was told it was a 4th gear run.

 

[PhilW]

WHP or BHP?

 

[Feel]

I've kind of lost track with your thread, Dave, are you happy with it without WI? My impression is, it's pulling back? I'd be chatting Kev up to have a look at the logs possibly even a logging session if he's not too busy.


Edit:

WHP or BHP?

Good point

Edit2:

And two of those Ibiza owners wouldn't happen to be the long-lost "geordie" clan would they?

 

[DPJ]

WHP or BHP?

Flywheel figure.

Thanks for your interest Phil. I'll pm you over the weekend (or earlier if I get the chance). The simple answer is - I don't think I've got the wmi setup right yet.

 

[PhilW]

ahh ok, did you log the car on the runs? whp figure would have been pretty sweet i reckon.

 

[DPJ]

:Edit2:

No, they've vanished. I think Jools has a VXR now.

 

[DPJ]

ahh ok, did you log the car on the runs? whp figure would have been pretty sweet i reckon.

No, I couldn't. ATW would have been better. The power line is remarkably similar to my MAF plots. What do you think to the similarity / difference in the JBS:Vsport graphs?

 

[PhilW]

Difference is the above actually run the car properly unlike JBS who stopped it when they felt like by the looks of the graph.

They 100% sure it was run in 4th?

 

[Martyn]

Dave, did they only do 1 run?
