Hi Paul..
Hi , Thanks for the detailed reply .
My
ECU number is INT Paul 1097 , it has fully programmeable maps , + extras both ALC and Launch control and the AUXs ins .
A Wide band sensor is connected to AUX 1 in . A 2.5 bar map sensor is employed over the stock 2bar absolute OE .
Engine is stock but with the addition of a fully worked GC head unit + matched inlet ports , with OE 8v Exhaust cam + Lancia Beta 2L N/A inlet cam provided by GC , the Cams timing is set standard with the OE marks.
I have no plans for ultimate performace with high boost in fact I run near standard turbo boost.
And am looking to save fuel rather than waste more , a little more torque is something I’m hoping for along the way.
I have 440cc injectors running 2.5bar with OEM EVO1 16v regulator fed by a DA-27 pump ,
fuelling now has plenty of head room for the heavy foot.
The exhaust is a one piece stainless 2.5inch straight through from the turbo back with the OEM exhaust manifold.
EGR and Exhaust cat and resonators where removed a long time ago.
The 8v kat ECU also has a knock sensor that is read by the ECU, it has never detonated or ran lean at all during fuel map tuning as I carefully made sure to do most of the tuning off boost around 3000 miles mapped.
However it did run intermittent lead / rich for a while with the Walbro pump , I spotted about to fail on the logs now replaced.
that pump had only made around 25kmiles off use 4-5 years before going bad , and it also seems they all do this at least in the posts I found regarding issues on many non Lancia cars. I would not known about this pump issue without an Enhanced ECU :) at least so early , Wideband logger
So I’m lucky.
It is of interest to me to compare the maps and other settings of competition and stock or mildly tuned 8v’s such as my own ,
at the moment I have no other maps other than my own in RP labs format for the ECU.
Also to check that my map is correctly setup with some reference , I would not simply copy data from A to B etc .
I always like to compare myself and learn before making any changes to the setup regarding Ignition.
I am aware of the damage that can be caused by bad guess work or more rather pot luck .
I have quite successfully remapped the entire Fuel map to suit my new injectors with the use of the Wideband via AUX1.
It was very rich to begin with as you can imagine , now leaving some 20% − 25% spare for future alternative setup.
Im sure theres more room for improvement regarding trims.
Im happy to share my map, "NOT OEM" freely , and with logs , I doubt at this time its perfect as I have only been tuning it for 9 months on road for the current fuelling also changing the pump and regulator due to failure mid way made for problems and redoing the whole thing twice,
fuel trim is still something of a grey area at the moment.
"It would be also necessary to make a structured list of well described engine specifications. Short descriptions like "C&B racing cams" do not help much, as depending on how you time them, completely different ignition advance could be necessary. Instead, for each cam specify at least advertised duration @ valve clearance, set valve lash, lift at TDC, maximal lift, valve openining and closing angles. Please do this even if you have stock cams, as I do not have specs available for the 8v."
The Head is fully reworked by GC , standard timing with a Beta 2L N/A inlets cam : Guy do you have this data , thanks ?
"How big is MAP at idle (at which revs)? How big is it at steady 80 and 120 km/h in 3rd, 4th and 5th gear (and at which revs)?"
Low points 750 RPM to 1200RPM @ + 177 to 400millibar .
I will pm you my map and last log file . looking at the ignition ,
it seems incorrectly setup I do understand some of those point don’t or won’t get used often , but still it seems not 100% .
"What is the highest temperature you observed in the intake manifold under load (consider summer months, with engine preferrably soaking heat in city traffic before highway use)? If you don't have summer data, as an alternative, let the car idle, but cover the hood and front air inlets with blankets. Wait until the radiator fan engages. As soon as it stops, turn off the engine and observe inlet manifold temperatures. After the peak has been reached, remove the blankets, start the engine and drive for about 2 kilometers under moderate to heavy load. Note the average temperature in the intake manifold during that time and subtract it from average environmental air temperature. Then add typical summer air temperature to this value, and report it back here. Please also post resulting logs of intake temperature as Excel charts."
I can take an inlet reading from the ECU ATC logged one from summer this year , and on from now.
Summer temp around 27c on boost 1.1 bar and 40c idle up to temp , Ambient temp around 20c
Winter Temp around 25c on boost 1.1 bar and 34c idle up to temp , Ambient temp around 5c
"Do you have at least some basic equipment to listen to engine knock? Did you try to optimize ignition in the low load portion of the map? I would recommend starting there first, as the risk to components is the lowest. “
Yes ,
Definitely .
this is the area I’m most interested in at this time. " the low load portion of the map?”..
In the image below , you can see settings of 10 increasing to 17 is this correct in line with OEM maps it seems out of bonk..
Many thanks and seasonal tidings.
Paul .
