Tune

[ImPrOvIsE]

I have just changed my oil and spark plugs and was now wondering where I can take my car for a tune.

Any tips on where to take it and what it might cost for just a tune.

ALso, there is some ticking noise which i presume is a noisy tappit. Is there any easy way to fix this?

A tune? As in dyno tune? Do you want to try and get more power out? I suggest Steve at SST, in Welshpool.

A noisy tappit?

Do u think a dyno tune is necessary for a stocker? Would it make much diff or would i be better off waiting until I get my exhaust done (however this wont be for a while yet)

I just thought that since Ive changed my plugs and oil i might as well tune it as well. My car is not running rough or anything though.

ANy idea on what this might cost anyone?

What are they going to tune then? I don't see the point till you do a modification they affects the air-flow. There is not much you can adjust except for timing.

Did you gap you plugs?

Plugs are already pregapped at .8mm. Is it worth adjusting the timing you think?

If you want a bit more power and better response. But I'd wait till you do a major mod, then have it re-tuned all at once.

One more question.

When checking oil, is it best to check just after running the motor(5 min), or like a few hours after.

The reason Im asking this is that there is a big difference between levels depending on when youre checking the oil.

After adding new oil last night (and starting it up for 3 min) ,then checking the dipstick, it was right on the Full mark.

And then checking this morning it was a fir bit over. I drained this excess oil

Try disconnecting your battery to reset the computer.. then drive it how you normally do.. that apparently retunes the computer to your driving a little i think?

as for oil levels - oil gets dragged up into the engine - hence it was lower after running it for a few mins.. it usually doens't take long to drain down again.. if the sump is full at cold things are all good.. if it's a little bit over i wouldn't worry about it..

if youve got no programmable ECU's or anything then theres not alot of point getting it tuned.

as far as timing goes, you can set that yourself, get hold of a timing light and make sure its at 20degrees btdc (i think thats what it is for an RB25)

when u say tappits do you mean lifters? RB engines have hydraulic lifters and they can make a bit of noise. unfortunately they cant really be repaired without alot of work. you can dull the sound a little by using a thicker oil... the other thing which could be ticking is either an exhaust leak, or the injectors may be noisy. ive heard a couple of SR's with noisy injectors but its probably nothing to really worry about

[puckish]

15BTDC for normal and 18BTDC for a crisper response.

Always use PULP

Throw in a good injection cleaner now and then

Reset ECU when you do ya oil or plugs. Disconnect batt and stamp on brake. Reconnect batt.

Change ya fliters when recommended.

Get a manual for things like TPS and Timing.

puckish - tps? what dat?
