with idle at around 1000rpm are these readings correct?

coolant 50 degrees and rising
inlet temp 23.75 degrees
battery 14v
co trim -50 (co is about 4% at idle and havent been able to get it lower, but ive only just got this software so now know what the co trim screw is at what should it be to get the co down?)
injector pulse width 2.4ish
lambda correction is 0. its not got closed loop but it does have a lambda connected, green top level 8 ecu
ign adv. 18 ish
boost valve 100%
idle valve modulation is 0? but if i unplug it the revs drop, then rise again when its plugged back in, is this right?
also the throttle pot goes from 0-68% it doesnt go any higher than 68% even if i open the throttle fully by hand. what should it top out at? i would imagine 100% but am probably wrong lol
all new sensors, new loom, msd chip.

throttle is just over 80degs flat out mate, so that needs looking at for sure, maybe just a simple cable adjustment

whats the exact reading on closed thottle? what ecu is it on? what spec?

you need to reset your base idle speed aswell

stu21t

hi m8,
ecu is a l8 green top with pectel version 3 baby board
msd chip and board for antilag/launch control, wasted spark
do you want engine spec?

throttle is at 0.99 degrees at idle/closed, should be at 0 shouldnt it?
if i open the throttle body up hand at the throttle body, not the pedal i cant get a higher reading still.

also checked the lambda with a multi meter and it is showing 0.85v at idle going into the ecu but the iaw doesnt read it? shows as N/A is this cos its not closed loop?

JTECH James

iTrader: (13)

yes it wont stream lambda if its dissabled iirc,

sounds like a tps issue there imo, idle reading is slightly to high, and flat out is to low.
worth looking into

stu21t

tps is new as is the loom will adjust it later and see how it goes, all the engine sensors are new and correcctly fitted/gapped.

what about the co?

JTECH James

iTrader: (13)

co is higer than i would expect, lots of possible causes tbh, air leaks etc

saph4be

how do you reset base idle on these sorry to hi jack thread

JTECH James

iTrader: (13)

warm it up to temp,
unplug iscv,
set base idle to 900rpm via the base idle screw under the throttle body (brass screw)
re connect iscv

idle should then remain stable

why didnt you go closed loop? your car is already set to run it!

stu21t

i didnt think i would benefit from it much, but i do want it now. lol
i will be sending the chip back over winter to get it added.
i still need to sort it as it is 1st anyway.

the engine is freshly build and theres no air leakes, all new sensors and loom, everything else seems fine,
just need to sort the co and tps then should be done.

Is your loom specced for the TPS you are using?

stu21t

yep, its reading correctly just not to the full range

Neil S

iTrader: (1)

As you work the throttle by hand does it hit 68 smoothly then stay there for the rest of the opening, or does it hit 68 as you get it to the stop?

Is the butterfly fully open if you look down the throttle body?

I had some odd issues with mine after I rebuilt the body - have you had yours apart?

stu21t

by hand on the TB direct or at the pedal engine on or ign on its the same
goes from 1-68 smoothly and thats where the tb hits the stop, fully open
it has been apart but its working properly just the tps doesnt read high enough
with a multimeter it reads from about 0.18v-4.4v

Neil S

iTrader: (1)

If the butterfly is moving as you'd expect visually then sling your old TPS on it and see what readings you get.

Are you seeing 0-100% on your SECS monitor?

stu21t

didnt think of trying the old tps. will also disconect the tps and see if it goes to 100% when its not on the tb.
i dont have a secs monitor.

stu21t

here the readings from when it got warmer.
rpm 880-930 ish
inlet press 494
throttle 0.99
coolant 72.5
inlet 36.5
battery 14.2
co trim -50
injector pulse 2.2
ignition advance 17.50
boost valve 100%


whats aux in? can i run a wideband with it?
and what should the co trim screw be set to? around -1.5/+1.5?

your manifold pressure value is also low for a standard cam engine
what cams are you running

stu21t

Bd14 in
bd 10 ex
lightly ported head 24.5mm(I think)
4x4 plenum with a 10mm spacer
grey injectors
stu said it was a little high?

Turbosystems

iTrader: (5)

you would be best getting it professionally set up and live mapped

stu21t

I would like to but msd are miles away and as I got thier chip with w/s, ALS, LC
I think it would b best to stick with them.
1 day I will get it there and done.

stu21t

been for a quick spin
this is what i got

at 6000 rpm full throttle
inlet pressure 2276 mbar
throttle pot 70% (full throttle, tps is new but something isnt right)
coolant 81.5 degrees
inlet temp 35.75 degrees
battery 13.5v
injector pulse 19.0
ign adv 11.75


do these figures look correct?


also still got high co problems
with the co trim set to 0 the co is 8% hydrocarbons about 1200 :0
the lowest i can get is 5%co and 700HCs with the trim screw at -50%

engine is new, bd14in bd10ex, greys, 8-1CR, ported head, new sensors and loom, msd chip.
engine was built by bluesprint motorsport so all cam timing should be fine as it was done on the bench, no air leaks, wasted spark.

any1 got any ideas?

stu21t

have also noticed that
injector pulse sometimes drop to zero
also sometimes the tps is a bit erratic, its idleing then the tps suddenly reads 17%for 0.2of a second and back to 0 again the 5% all inless than a second, obviously isnt me doing it.
will double check the old tps see how that is.

andrewg

some times alternator can interfear with readings

Turbosystems

iTrader: (5)

make sure you have routed the ht leads away from sensors etc
you will see 0 ms pulse width, this is the ove run fuel shut off

Neil S

Did you try that old TPS yet? You definitely have an issue there, so I'd be fixing it if I were you, then seeing where you are with the rest of it.

jason 3dr

did u sort out this prob as iam having the same prob

stu21t

i have found and sorted loads of problems recently
quite a few since getting the iaw monitor.
found 2 inlet manifold leaks, and 2 boost leaks (ive made a boost system tester)
finally got the tps working correctly, now reads from -0.30 to 82.4. the metal slide on the side of the tb with the spring was bent, stopping it from opening fully, and also gave a stiff pedal, neither of which i had noticed
i have also found,
low fuel pump voltage, dodgy pump (even tho was a new 044 when i bought it a few yrs ago and has hardly been used)
dodgy fuel pressure regulator
ecu voltage supply was a bit low

i still have high co's at idle.
i sent stu @ msd a copy of my data log file from idle and a copy of the co machine readings,
then rang him today and he couldnt have been more helpful.
as i am happy that its not a problem with my engine/car its probably down to the exact cam timing being slightly different to what the chips been specced for.
so he is sending me 2 new chips with different idle fuel strategies for me to try.
so i can go to my m8s garage hook up the co machine and have a play.
so my car wont be off road at all and all i gotta do is send back the chips i dont need.
couldnt ask for a better service really.
will let you know how i get on, im hoping to have it sorted after work tomorow.

jason i take it you havent changed any spec on your engine while it was apart?

otherwise it must be a set up or sensor issue as it was fine before

foreigneRS

looks like the software was a good investment then as it's saved you either a damaged engine or a few hours of labour at a tuners

jason 3dr

havent changed anything

JTECH James

iTrader: (13)

get national day out the way, were all off on holidays for 2 weeks now, when we get back we will look into it in more detail

i had the perfect car in today for the testing i wanted to run, sods law

jason 3dr

changed the tps ,made no difference ,fuel @idle 14.7 5th gear 70 mph 3000rpm 11.2 ,then unpluged the lambda @idle 15.5 on a run 13.9
but if i give it lite throttle to bring boost up to 0 instead of - ..14.7

JTECH James

iTrader: (13)

have you got the iaw on it? send me a log file if you can and il take a look

jason 3dr

not yet

JTECH James

iTrader: (13)

bloody hell

jason 3dr

james,i know its been a wile but just got car out again ,driving it on wednesday lamda unpluged fuel at idle 14 on a run it went to 20 % .rich has the iaw now so it will be going on this week will let u know the readings

ossie cossie

I am thinking of getting one of these kits soon for my escos on a P8 ECU but im not very computer savvy is there any help if i get stuck, i am also in Australia so that does not help i will never be able to get it live mapped. There are not many (if any) cosworh experts here. I would hate to give it to someone to fix up and have to pay them if they dont know what they are doing, they could f@#k it up, i could do that for nothing.

ossie cossie

James @ M Developments.
If i were to buy one of these IAW monitors for my escos (P8 ECU) could i then help out other cosworth owners here in OZ? say for instance a freind that has a sapphire with an L8 ECU.
