Hi guys,

I have an Aspec GT3574R single turbo fd with the following mods.

ASPEC GT3574R turbo kit
ASPEC 450R fuel system with 1680cc secondary injectors
Koyo rad N flo
Large SMIC
Innovate MTX-L Wideband
Datalogit
HKS blow off valve



Where I live there are no tuners for rotaries. Is there someway that I can have the car tuned online and pay for it. I am looking to tune the car at around 13psi. I can provide further details if required.

Thanks...

 

No. Tuning is based on testing, datalogging, adjusting the maps, repeat...

 

Someone might make you a map that is close, but unless the engine is exactly the same, it will still need AFR tuning and maybe timing tuning.
You can either move or take time off to drive to a tuner.

 

I've done it before with someone in the states with a precision 6265. Its a very tedious procedure and requires a lot of logs and explanations. It takes a long time and you tend to leave it conservative since you can only trust your data so far.

Thanks guys.

I don't mind if it is conservative as long as it is safe as right now I don't know if I am sitting on a time bomb with my map...

Thanks

 

What makes this difficult is that it's an FD with a standalone--basically a heavily modified car--instead of say an Evo with a turboback exhaust and a stock ECU (which can be reprogrammed).

 

You can also save up some money and ship it to a tuner, thats what I did.

 

You can't tune a car that way, you can have someone upload a map that may work ok and be safe but you won't know for sure unless you have a wideband to check it.

 

I've talked to a couple tuners about doing this but none have seem interested in testing. My idea was to connect my laptop to my car (datalogit), and use gotomeeting/webex/joinme, so the tuner would have remote-control of my computer. Essentially they would have full control of the car/tune as if they were there. The only downside I could see with this scenario is that they can't hear/feel things going on.

Would seem like a pretty profitable way to do tuning. They wouldn't even have to leave their house.

 

Using a VNC to connect to your laptop is a waste of effort since you cant stop the pull after its happening. Doing logs is the only way to do it. A wideband is obviously required.

Yeah I guess I was thinking more of a tune for myself in the scenario. I have a wideband installed (permanently) in my car and is wired to my datalogit. I also have a wideband gauge next to my oil temp gauge. My thought was to do the runs, stop immediately for knock / lean situations and let the real tuner read the logs through the VNC.

 

In the real world its impossible to stop due to knock (unless its some serious knocking which you can hear, in which case your motor is blown already), the only thing you can pay attention to is the wideband and the sound of the car. You look at everything else after the pull in your logs.

I just don't see VNC being any easier to work with then to just send him the logs over messenger/e-mail/skype and have them look at it on their own computer at proper resolutions and no lag delays. Then change the map on his computer and send the map file over for you to load onto the car. That's more or less how I did it anyway.

Shipping the car to a tuner, at this point, sounds much more reliable than a tune made via remote desktop. Actually, you could tow it yourself with a rental.

 

Using Wargasm's write-up set up your laptop to look something like this.

Start loging AFRs and making corrections.

Any cell that you have a knock number greater than 40 take a degree out. (later drop the limit to 20)

Use AFR targets close to this. Notice this table goes to 24 psi.
Go leaner than this with meth/water injection.

 

^ AFR Targets are conservative 12 psi and up.

I've done remote tuning using Team Viewer remote access software. It works decently well if you have someone on the other end that is competent enough to run the dyno. It's far more cumbersome than being there yourself, but it does work and there are some rather high end tuners using this approach.

 

Most people can tune their own non-boosted cells with just the commander.
I prefer this method out of boost. Hills can add valuable cells.

Having the map sorted out well before you bring it to a tuner reduces his workload.

If you become comfortable in vacuum then start your low boost rows.

Use the excel program to compare and smooth rows.




For boosted rows trust the corrections given by this sheet.
It is that easy.
