Anyone In Vic Able To Lend A Hand With A Road Tune...


Recommended Posts

Howdy guys. After a few years of DIY tuning the car I need a final hand by someone more experienced then me to do a final on road low RPM tune (as in, everything in the higher RPM's has been dyno tuned)

Getting sick of log, alter, upload, log, alter, upload, etc etc etc etc, makes driving the car more of a chore rather then a happy drive. I'm in the western suburbs and not really fussed if I need to drive out. Will pay in cash, alcohol, sexytime, whatever.

Also, car isn't a skyline if you've guessed lol.

Even if I could get some usernames of people i could PM or email or whatever that'd be tops. heaps of places here to dyno tune but (well for obvious reasons) not many who can do a good on-roader.

Spanks.

if u know the basics and have the tools you should be able to do it yourself

what ECU and software are you using to tune it? what cant you do or dont understand yourself?

I do understand the basics....It's mainly the timing side of things I'm not 100% in yet.

ECU is an adaptronic e420c. Software is WARI V8. what can't I do? is drive and tune at the same time.....That's the main bit. for now i need to drive, log, get home, go over log, correspond with map, alter map, save map, upload to car, road test.

AFR's are pretty damn good but it's mainly timing.

Car is N/A aswell.

get a girlfriend or friend to drive and just drive in normal mode, ie you dont have to load it up mega to tune the ignition timing

and basically dial in as much timing as you can without knocking, when you reach the knocking point, back off 2deg and your done

i did this on my gtst with a powerfc and thats all there is too it really, make sure you dont dial in too much

ie add +2 deg to the whole map, plod around (dont load it past 3k) and see how it knocks

then if you see no knock in low area, repeat again

i was able to add +12deg under 3k on my GTST and the results were amazing

never laod it past 3k with that much extra timing but under 3k should be ok

this should change the car from normal/sluggish/doughey to sharp and crisp

Thanks for that writeup mate.

problem is, for whatever reason it is, my whole map in untuned (ignition timing anyway) areas are all 35deg+ from 1800RPM onwards. so I'm in two worlds as to where to start. Do I dial back or advance it more. Hmmm. So much for forking out thousands on a "tune" and getting a "tuned" car back. Ha.

you add more timing on the map (advance it)

the more you advance it, the more efficient the engine becomes, but the more likely it knocks / detonates

so you advance slowly in small increments until you find the knocking point, and take of 2deg

lets say at cell 4,4 its the load point for 2100rpm to 2400rpm

and its say 18deg IGN Timing. drive around go past the range under normal acceleration or whatever and see if it knocks

if it doesnt, change the IGN timing for that cell to say 20deg and repeat

can you build a kncok map with your software?

datalogit does this very well

you bascially drive around and it logs all knocking values onto the map tracer format

so for every cell you can see min/max/avg kncoking

then you know which cells have too much timing and which cells dont have enoguh timing (ie knocking is 0)

If you know your way around a dyno, Sam (Dr Drift) may hire it out if he likes you enough :)

Quite reasonable rates as well and in 1hr of dyno time, you should be able to touch up the whole map and do a power run.

Shite, you can even preserve your license, minimize car sickness and do it right with no chance of an accident on the dyno.

Gizzmo Kmon, Knock Box etc, is ESSENTIAL to tune knock properly if you're just starting out.

You can pick up knock quicker with one of these devices than by a normal human ear, simply because you can filter out all of the noises such as open wastegate, valvetrain, etc.

Good book on general dyno/engine tuning, including tuning ignition for MBT: http://www.fishpond.com.au/Books/Nonfiction/Transport/Automotive/General/9781934709740/?cf=3&rid=224650787&i=1&keywords=dyno+tuning

Google Tuning for MBT as well for a quick primer. You need a dyno and a knock sensing device to tune MBT properly.

Trent @ Status is quite familiar with Adaptronic, and when i had the GT-T, we would go out a couple times on the road, Trent with the laptop, and he'd make sure everything was hunky dory during normal road cruising. He'd have the map up and change things if need be.

Would highly recommend making the trip if you want someone very knowledgeable behind the laptop whilst you're driving.

Hi mate, any contact details for Trent @ status?

Thanks for the tips guys aswell.

Major thing I need to sort out is how to set up the knock filter by first filtering out all normal engine noise. good times ahead.

Forgot to mention a knock sensor is installed and working but the filter doesnt so it registered EVERy noise. No BOV or wastegate, tis an N/A car.

    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
    • One other thing to mention from my car before we reassemble and refill. Per that earlier diagram,   There should be 2x B length (40mm) and 6x C length (54mm). So I had incorrectly removed one extra bolt, which I assume was 40mm, but even so I have 4x B and 5x C.  Either, the factory made an assembly error (very unlikely), or someone had been in there before me. I vote for the latter because the TCM part number doesn't match my build date, I suspect the TCM was changed under warranty. This indeed led to much unbolting, rebolting, checking, measuring and swearing under the car.... In the end I left out 1x B bolt and put in a 54mm M6 bolt I already had to make sure it was all correct
    • A couple of notes about the TCM. Firstly, it is integrated into the valve body. If you need to replace the TCM for any reason you are following the procedure above The seppos say these fail all the time. I haven't seen or heard of one on here or locally, but that doesn't mean it can't happen. Finally, Ecutek are now offering tuning for the 7 speed TCM. It is basically like ECU tuning in that you have to buy a license for the computer, and then known parameters can be reset. This is all very new and at the moment they are focussing on more aggressive gear holding in sports or sports+ mode, 2 gear launches for drag racing etc. It doesn't seem to affect shift speed like you can on some transmissions. Importantly for me, by having controllable shift points you can now raise the shift point as well as the ECU rev limit, together allowing it to rev a little higher when that is useful. In manual mode, my car shifts up automatically regardless of what I do which is good (because I don't have to worry about it) but bad (because I can't choose to rev a little higher when convenient).  TCMs can only be tuned from late 2016 onwards, and mine is apparently not one of those although the car build date was August 2016 (presumably a batch of ADM cars were done together, so this will probably be the situation for most ADM cars). No idea about JDM cars, and I'm looking into importing a later model valve body I can swap in. This is the top of my TCM A couple of numbers but no part number. Amayama can't find my specific car but it does say the following for Asia-RHD (interestingly, all out of stock....): So it looks like programable TCM are probably post September 2018 for "Asia RHD". When I read my part number out from Ecutek it was 31705-75X6D which did not match Amayama for my build date (Aug-2016)
