1000km/1 month service - diagnostic computer

**unity** · 18-06-2008 08:05 PM

Hi everyone, I was interested to find out whether you have any knowledge about the diagnostic computer Honda uses during servicing?
Is the computer able to adjust car settings?
I am finding that after this initial service the overall performance of may car seems to be more sluggish than prior to the servicing? Has one one else had a similar experience after the initial servicing?

The Honda Diag computer mainly looks for faults and does any firmware updates for the ECU. As far I as I amware its not tunable like you can do with an aftermarket ECU.

I know when I was in the dealership it was used for just doing that.

Don't know if anyone remembers the BA XR6 Turbo getting a boost cut, to slow down warranty claims on gearboxes and diff's all to do with the ECU firmware.

Hope this helps.

sometimes you do feel the difference, not by increase of power but smoother revs etc.

but yeh its funny to know people do think that, psychological satisfaction.

i don't think that is a problem, your still wearing in the car until 5000km, and your not hitting vtec or flooring it until its worn in either.

Yes, I have to agree with you there. Most of my driving has been city driving. I have only managed to get on the freeway a couple of times. However, I notice the car's performance is much better at higher constant speeds rather than accelerating and stopping at traffic lights.

If I think things are not improving maybe shadou can have a test drive one day and tell me what he thinks. I dont live far from Mitcham.

worse comes to worse if its not a legit issue and you think its slow change your headers/extractors it'll make a big diff to stock.

give it a good squirt to redline every now and then, not everytime you take off, from near day one and you will have a better running car.

Thanks for the advice. I thought it was not recommended to red line it until the car was more broken in ie around the 5000km mark.

What car was the loan car you drove?

My 6MT feels faster than before after driving around a 5AT Euro or CRV or Jazz lolol

But yeah beyond that, the car does accelerate smoother after the sludgy deteriorated 10,000km oil gets replaced.

I let mum's euro get to about 100kms before the first redline.

To give you an example we had N16 loan cars at work. I got one brand new, one of the sales manager had another and a chick in service had another. I wasn't light footed, the salesman had an even heavier foot and the service chick was gentle.

Yes there was a different in how they all went. The salesman one was the quickest and the sevice chicks the slowest.

As I said don't redline it everywhere just every now and then and you will have a better car. Mum's is at 85,000kms now and no mechanical probs, is great on fuel, goes well and is happy to go to 7500rpm

Agreed.i redline mine 2-3 times a week.It seems to "wake up"the ECU.
