Re: ignition timing

On what fueling were you targeting 11.5-12* degrees at redline? I’m tuning for ethanol now on E30 and currently have my timing at 12* degrees at redline. I was obviously speaking of pump gas. With E30 you can run quite a bit leaner and add a ton more timing. If "redline" for you means 650...

Re: Am I safe to use this tune?

Yes, the CP-e CAI and the CS SRI have stock-like diameter MAF housings, and also the tune will adjust for fuelling differences.

Re: Pops and Crackles Disappeared

I found that when you let off the gas, you have to very slightly apply a little pressure to the gas pedal to get the pops and crackles to work sometimes. This is pretty much the expected behaviour when not disabling decel fuel cut completely. After logging, noticed that I wasn't dropping below the ...

Re: Disabled DTC still showing up

Check again the list of disabled PIDs displayed in the tune options, sometimes when disabling a PID the VT software re-enables the already disabled ones, or when selecting multiple PIDs to disable it will not disable any of them. The U2064 usually pops up when you connect and/or disconnect the OBD r...

Re: Tuning Troubles

You can raise the load limits to like 2.4-2.5, but the targets not above 2.3-2.35. I hope the rods will never tell you why :) On a worse fuel however which doesn't allow for too much timing you can go higher, because in the end it's about the cylinder pressure and actual torque.

Re: Tuning Troubles

The safe limits for a stock block is pretty much the limit of factory fuelling in therms of power (350-380bhp, depending on the fuel), and in therms of torque it's around 500-520Nm/370-380lb*ft (which is also the limit of the factory clutch). Also the lower limit of the above mentioned torque values...

Re: Tuning Troubles

More or less this way, basically you set your load limits (not targets) to values that are known to be safe with your setup (depending on your setup, if you have forged internals or not, if you have an upgraded clutch or not, and so on) and then you target boost that will result in an airflow which ...

Re: Tuning Troubles

Yes it is, but it's less consistent and you don't have per-gear control over it, which means you will still have to involve the load limits somehow. The logic of the ECU firmware (which we do not alter, we change only the values in the calibration tables) has more features built for managing the loa...
