ok, trying to get rid of this Kcontrol 100% problem and this ultra-rich behavior at higher rpm; i tried lowering ignition timing, up to a point where i felt i lost power. so i stopped. still no go. then i started lowering knock sensitivity (putting higher values) but i was so much way off! then I tr...

Thank you very much for information. (i think my friend mechanic mus have that in his toolset) my oil use is 1 liter for about 10 000 km wich is on the edge of "normal" oil use from the service manual. even if not catastrophic, it is way up from almost zero oil used before the camshaft/prings & reta...

The car runs fine, sound good, no smoke, temperature stable, pulls better than my wife's stock one from 2k to 7k. no difference before/after changing the plugs. i will check the plugs soon, will post picture and careful about order, 1, 2, 3, 4 this time. leaking valve or poor injector... the only cl...

I changed my sparks plugs today, sadly i was not careful at wich is wich (mabe cylinder 3 was the correct looking light brown color) ok, happy to put new ones, but wondering if tuning is that bad giving plugs such a disgusting aspect. Along with changing the plugs I installed an oil catch tank, beca...

there is a chance that correct gear calibration in the ECU would by consequence solve the IMA problem without flashing IMA

what do you think ?

so that makes 2 problems with IMA :
- rev limited to 7100.
- changing final gear suppress regenerative braking.

Thank you for your help. IT WORKS! The Kcontrol now looks stable between 40 and 55% while driving. I had to bump up the knock sensitivity around 3000rpm AND from 5000 up. I did that with VERY small increment, so it took me time. the behavior seem this : -> when Kcontrol MOVES UP ( even if it stays b...

I lowered the limiter again to 7250 rpm. No need of headlights, it is just the IPU that is upset above a given rpm. Maybe around 7300 or 7350 was the trigger. I drove about 1000km of various styles, the problem did not show up, at all. BAT volts is variable but this is normal for this car. = no prob...

i'm on it, but i have not understood enough to explain it to the tuner properly (things are similar on his cosworth, but strategies looks different) sure he decreased advance in most of the main ignition tables. i thought the knock control tables were showing their effect by making "knock retard" so...

in the area where i see K.Control go to 100% (it always starts at 55% ...) in what increment should i reduce advance and knock sensitivity (up = reduce sensitivity) ? advance -0.5° ? sensitivity +1% ? do i reduce only the specific -blue- field, or a group of 4 fields -blue and white near fields- ? Y...

Thank you very much for this precious information.

- I will now monitor K.Control ===> is it I need to reduce advance, or knock sensitivity due to my camshaft ?

- I have unchecked "use AFM" ===> this should end the problems of the intake ?

If not then i will go back to stock intake.

here is a much better datalog

there are two 3rd gear pulls, with a cooler weather ambient temp 19°C

and two 3 rd gear pulls on a rather flat road, one reads lean the second looks rich ???

here is a graph where i firs spotted the problem : https://dl.dropboxusercontent.com/u/42724337/problem-graph1.JPG you see in the middle the A:F jumping down ? does the lambda overheat ? I think i run in fact too lean... anyway i dont trust measurements because there are two trends instead of one. s...

i'm disappointed : on two pulls one is correct and have AF ok btw 13,1 and 13,4 the second one is dull, no power and the AF drops from 13 @4000rpm to 11@7000rpm i see no reason : same altitude, same temps, same hour, same map the car is in the same column 9 of the table. Ltrim stays the same Strim z...

it took some time but I unchecked AFM and fuel modification have an effect now . anyway i find another inconsistency : if i do an XY graph WOT checked X = rpm Y = A/F I get two completely different A/F behaviors for the car : one seem to follow map fuel table (maybe too lean in some areas) around 13...

We had to uncheck "use AFM" in order for fuel modifications to actually work. the DynaPack and the CRZ in 5th gear made all the curves with strong oscillation, making decisions less obvious than expected. Charles of Monstaka said 5th gear is to preserve gearbox. 7300 rpm limiter worked ok. We came t...
