the ecu should be capable of running the car (in a crude manner) to a better standard than it sounds like yours is. VVT is switched by the ecu.
2 months is aweful btw. I've fitted ITBs in a day, including fitting aero catches.

i did say they were taking the p155 with the car on the phone , i have been honest with them and ringing them every day , i also told them the throtlle bodies and mapping can be done in a day , just seems like they havent got a clue with clio's
ZOMG. Didn't realise it was megasquirt. No wonder it's only £2100.
Fail
Fail
ITB'd MK1
Probably got the one we wrote for GDI and K-tec from Jenvey LOL
ITB'd MK1
Megasquirt isn't an organisation, it's an open source project.
multiple reasons. It works in a different way
ITB'd MK1
yes, should be able to. All that's needed is a simple output that switches at around 1600rpm
So it's cos £3100 really then, and it doesn't work.
After he was raving about this company as well!

Does the oe ecu do alot more than just the dials then I take it?
Did he already have the 428's fitted?
ITB'd MK1
just had a look at that write up they did and it said the car was under 160. That's oddly low and didn't realise cams had been changed. should realistically be in the high 190s with ITBs and 428s. Does indeed sound cam timing related now I know cams have been done.
ITB'd MK1
That's about it.
ITB'd MK1
nah, no way, 428s are too mild for that. not a big top end gain from them. 421s maybe. Perfect cams for ITBs on stock compression
ITB'd MK1
yeah agree with that bit, although the power is quite late in the revs with a not very good spread. Wont see a big bump in bhp figures when added to ITBs though, just a far better power and torque spread once you have throttles
ITB'd MK1
try some 421s, seriously, they s**t on 428s

said all along nick, go omex, u know it works, i know it works and the whole dash setup works too, not landing you with another bill to go stack dash just to see whats going on. id seriously question you having cams tho. i was on the understanding that they look different to stock cams when viewed through the oil cap, danny/fred can you confirm this?

if that had cams when it went in and made 160bhp before any work then guaranteed the timings out, who fitted the cams?
i'd be on the phone to TDF myself

was based on a he knows it works senario
ITB'd MK1
they do look a little different yes
Coupe/Defender V8
ouch, just poor mapping surely? 428s don't really compliment jenveys anyway, join the club on that one
You'd be able to tell if they were very low milage new (assuming they are) cams anyway compared to a set of high milage standard/OE cams

Sh!t me £1k to fit a Megasquirt 
Umm err yeah basically what everyone else has said.. I know some guys using an MS but just because they want to do it all from their garage and they openly admit it doesn't run as well as exactly the same setup in another car that runs Emerald instead..
Pretty sure that a friend of a friend knows these guys as well.. hmmm

on the DD roller which they have you would usually see on a low top end 195bhp with 428's... thats the worst I have seen. Best on stock internals has been 212 with 421's.
428's on ITBs dont give substantial gains.
the OE ecu is left in to run the clocks, and fan if you want.
unless the ECU has CAN facility you wont run the dash.
the graphs will give the cam timing away usually... but I cant seem to see them
Low down stuttering can be down to
Accel fueling
fueling in general
ign timing
balanced bodies or not (that should be pretty easy)
ITB cars should run perfectly and pull from 800 rpm all the way.
The cam phase shifter is a simple +12v switch that actuates the cam to advance 16 degrees at usually 1800 rpm and above "x" throttle angle
decent systems and maps will check and set this to switch off above "x" rpm as well as there is usually a cross over point on the map where the engine doesnt want the cam advance.
however with and mod spec cams it is usually left advanced.
If you need more info on ITB spec cars, let me know
