Ok, so you're running on peters basemap atm.

Can you email that to me so i can open it in my obdtuner so i can check the parameters? (just pm me) 

Your CS map sensor will be a regular 2bar one, not a tmap.

 

[TIP]

still waiting for the interface cable to arrive (hopefully friday) then I will email it to you ( thank you)

 

do i need a TMAP sensor or can I use the CMS supplied MAP? 

 

just heading off to the workshop now with my cheap ebay OBD reader will post error codes asap.

[smiley]

In odbtuner you specify if you use the CS 2 bar map sensor, or a 2.5 bar tmap.

If you have a tmap sensor however, the wiring of your temp sensor (the one between air filter and throttle body) and the map sensor are combined. 

So tmap is not just a tick in the software.

 

Peter is not known to make mistakes in his basemap.

He will have asked you for all your cars variables, before creating the basemap for you.

Can you post what you emailed him on parameters?

You can just use the CS MAP sensor, that's what I am doing and its grand. Get it up and running properly before faffing with a TMAP. As for your dodgy injectors, have you checked that the fuel rail is getting the vacuum feed from the manifold? It looks like it in the picture before, but thought I would ask. The map needs to be told what the vac/fuel rail/rail pressure setup is, but as mentioned, Peter is pretty thorough and I would be very surprised if there is a mistake in the map. 

[TIP]

regarding the parameters sent to Peter. map sensor number and positions- cos supplied and in manifold Tmap- no oon phone so struggling to copy not paste email I sent to Peter?

[TIP]

error codes p1512 and p1514 any iideas?

[smiley]

P1512:

- brown ecu relay in the back making bad connection - blue connector behind header tank bad connection (not corroded!)

 

P1514: - scangauge set to showing more then 3 values - faulty injector - faulty map sensor

 

My first bet is on loom of doom, so clean and check the 2 connectors behind the header tank first. 

[TIP]

due to the throttle dropping out I have already checked and cleaned the two connectors. going to get some new spark plugs too as just occurred to me these have done 20k +. vauxhall triple electrode best to go for?

Same code I had yesterday when wrong Throttle bodie and map sensor and injectors were selected on acidpopstar car yesterday Put right parameters on everything ok

Also same symptoms

[CHILL Gone DUTCH]

got an email from Peter, my wayward ECU has arrived , been updated and posted back so hopefully that will arrive early next week.

 

Have booked auto glass to fix this mess

opps must of dropped a hammer 

 

other wise today was spent tidying up and fettling the installation to a point where I am happy with it. (killing time really untill ECU arrives and autoglass fix the windscreen)

decided to cut the fuel lines and reroute them to the passenger side, not completely happy with this as didn't want to cut the pressure test valve off , but the existing pipe is all bendy. may live with this ???

 

the belt was still worrying me ( even with the fuel rerouted there is a lot of fuel filler pipe work quite close so fabbed up a guard from some spare ali

 

still contemplating the PCV solution , more on this as I make a decision

 

 

 

 

 

just check your fuel lines are correct just noticed that you have changes your fuel pipes

Mine went for the three cylinder option when she started as well.

It was so simple that the plug into one of the injectors was forced out when I bolted the injectorrail into place.

[TIP]

right frustated now!!!

 

all connections cleaned and checked (loom of doom, injector plugs, throttle body, ecu, map sensor)

injectors checked (all are delivering fuel)

 

this is the engine configuration I sent Peter (I cant check this yet as I'm waiting on the OBD interface to arrive) but I cant help thinking that Peter wont have made a mistake

engine starts and hunts for revs and then drops a cylinder, if I give it some revs the throttle is silly responsive , the very slightest pressure on the pedal (2-3mm) sends the revs immediatly up to 6K.

 

as soon as the misfire develops (10-20 seconds) I get no response from the throttle and the EML lights up with P1514. Cleared this code a few times and each time it comes back with P1514. (as well as Smileys reading of this code (thanks)I found reference to it being something else

(the dreaded p1514 is too much intake air flow, the ecu then gets the hump. - Vocky)

 

 

I guess Im stuck untill I can connect the laptop and check the base map? although it has to be something simple , as I said cant believe Peter would make a mistake

[nicollow]

Perhaps the throttle body is incorrectly wired?!?! Throttle shouldn't be that sensitive

[Captain Vimes]

You're welcome to borrow my cable but realise I'm not exactly close to you....

 

Once you have the cable you can log what's going on and hopefully all will become clear.

[vocky]

if an injector isn't firing and still does not fire after moving it to another cylinder then replace the injector, I have seen two duff LSJ injectors recently. 

[TIP]

excellent the cable has arrived , so I am off to the workshop to get a log to send to Peter and to check the configuration, update soon  

[TIP]

configuration of the ecu is correct. have pulled the loom apart again and checked the wiring of map, injectors, and throttle plug. still badly misfiring have done a short log and sent to Peter so fingers crossed he can shed some light on the problem

[CHILL Gone DUTCH]

Just pmed my email address can you forward log to me please Chris

[TIP]

Peter says The error code P1514 is set when measured engine airflow does not match estimated engine airflow as established by the throttle position sensor. hhave checked joints between 1.TB/SC 2.sc/manifold 3.manifold/head
