Cost effective ways to reduce under bonnet temps

[davekmoore]

From memory you need to tap F11. Ring Jason at Plus and ask how to connect

Is this Automotive Plus?

[Magpie]

Yes.

ECU does not show up as a drive on the computer though. Neither F11 nor any other F button changes any of this.

It won't. The ECU will be a serial port on the computer, and the ECU Manager uses the serial port to communicate with the ECU.

Watching that video it talks about needing to setup displayed/watched outputs first before you log. When you want to log, it talks about switching to another page and start/stop the log (probably via F11) and this has then started/stopped the logging process in the ECU and the software on the PC can keep a copy of this data for later saving/expo/playback etc.

While talking to the fabricator who's making flanges for the brake vents he suggested the air filter is in a bad place and needs to be out of the engine bay and lower down in cooler air. He also thinks the air flow is probably restricted by the standard AFM next to the filter. And he'd like to replace the steel intake/intercooler pipes with thinner alloy ones and to make them longer to minimise the amount of rubber hosing, all in the interest of avoiding heat soak. As a layman I can see how this all makes sense. It would be good to have opinions from people who I'm not going to pay to do the work though!

Yes, I'm still trying to find a tuner who will respond to messages about sorting the Haltech and to find out how to log data to send to said tuner so I can properly diagnose what needs doing.

I wish I was at home and I could connect and help out. My PS1000 has a USB cable and not a serial cable, however I have a laptop at home that has a serial port as sometimes the USB to serial do not work, the Innovate uses serial connectors to programme.

From memory I plug the USB cable into the computer, power the car, start the software and then click connect. Is the other end of the cable plugged into the PS1000 (silly question I know), from memory it is a D type USB. Try unistalling the software (and deleting the directory) and reinstalling.

Dave you need to find out how the car is tuned. If is tuned using the MAF (not AFM that was the flapper door type on the na6) then deleting it will cause problems. The MAF is alot less restrictive then the AFM and I wouldn't have thought it would really be an issue with a turbo to mechanically draw air in, but I'm not a turbo person.

If the tune is MAP based (manifold absolute pressure) then yes there is no need to keep the MAF.

As previously mentioned the MAF incorporates an air temp sensor. If the haltec is using this for intake temp removing it could play havoc with the ecu until you get the tune sorted.

If what ever your using to display intake temps users the temp sensor in the MAF then this channel will disappear or read an extreme value.

Try starting the car then disconnect (pull the plug off) the MAF and see if the engine dies. If it does the ecu must be using it for something.

If nothing happen the tune is almost certainly MAP based so you just need to work out if it's using it for temp. Once you have the haltec connected to the laptop pull up the gauges it similar style page and look at your intake temps. Then go and unplug the MAF and see if intake temps change.

Turbo cars are less needy of cold air intakes because the turbo heats the air then the inter cooler cools it again. my understanding is that the small intake air temp (and density increases that goes along with cold air) is lost in the scale of how hot the turbo makes the air. The inter cooler also cools more efficiently the higher the difference between your charged air and the "cooling" air.

Given how tight your at with budget at this point I wouldn't be too inclined to worry about it (assuming your intake air temps are fine under load and only high at idle). Particularly with another tuners cost coming.

Thanks for the thoughts. I'll try them. For the avoidance of doubt the following is only a reflection of how confused I am, not of your help:
Do I need to also stand on one leg and face any particular direction?

Keep looking forward and remember to breathe

No, but you do need to poke your tongue into your left inner cheek whilst chanting to the EFI gods... "carby are for old fools... dizzies are for the mad"

The former didn't work. The middle must be true as the tuner just plugged straight in last time I was there. I will try the latter, because my life would not be complete otherwise.

The Haltech forum is painfully slow but you will get what you need in time.
There should be a Haltech ECU manager icon on your laptop after installing software. Open icon. Plug usb cable into laptop and from drop down menu in ECU manager click file and then connect or F5.
Once your in you won't have all the icons like the video you have to set that up but after playing for an hour or so you will be an expert.
From there you will have all the settings down the left side of the page and you can open them all and adjust parameters as you like. Stay away from all the fuel settings.That is where you can detonate things. Leave that to the tuner, but the idle, cold start, alternator control settings,ect, you can happily play with and you will feel what adjusting these parameters does while your sitting in the car. There is a info/help menu on the right of the screen that tells you exactly what range is recommended whenever you select a setting.
It really is very interesting and you should learn how to do this because taking your car to a tuner to adjust idle up by 100 rmp will drive you nuts.
Give me a call if you like Dave, Scooby is 10 feet from where I watch telly and I can connect up in 2 mins.

I'm not sure if the Haltech USB cable is proprietary, mine is left permanently connected to the ECU. Did your previous tuner leave the cable?

Yes he did. Thanks for the thought.

THANK YOU SO MUCH!
Deleted the software. Drank beer. Removed the directory. Defribrillated the laptop. Went for more beer. Drank some of the new beer. Reinstalled the software. Started the software from the desktop icon and IT CONNECTS!!
Help from you Richard, and direction from others on this forum has once again saved me from complete madness (wife, family, work colleagues, everyone else who knows me will disagree, possibly correctly).
No time to play with it tonight (ooh err, Missus). Maybe tomorrow.
How sad is it that this forum (hooray) provided answers before Haltech's (boo) did?

Will any devices smaller than a laptop do the same job?

PS My laptop might be odd, but the software only works via the desktop icon, not via the Program list/directory hierarchy.

Congrats, remember to keep breathing now.
