Was turbo tuned and now built engine and question on tune - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Evil Rocky · 06-20-2020, 11:48 PM

So I had a stock FA20 and was turbo for about 13 months and now going built engine. I was on a conservative tune (9psi and doing 285whp on 93 and e85 10psi 315whp) I am swapping to same compression engine just a closed deck outfront motorsports, titanium retainers and valves only major change is to fluidamper and the rest just upgraded cooling mods and just new timing chains, tensioner, coilpacks and spark plugs.

I will break in engine soon and was wondering if need a whole new tune or can I break in with current tune and then once broken in get a full re-tune to go with built engine.

Thanks,

Should probably ask your tuner this.

just use the most conservative of the 4 maps you have from your tune

I emailed my tuner and no reply in 4 days. I am just asking here since hope in a week will have everything complete and want to start the break in.

Ah shucks that sucks. I’d go with the post above. Use the most conservative map. I’m guess since the compression ratio is the same there shouldn’t be much of a difference but I’m no tuner. Good luck man.

Do you have control over your right foot?

Drive it.

If there's something amiss with the installation you may not know for some time, whereas if someone we're watching your datalogs with intent to re-tune, they would catch it.

It SHOULD be ok for break in, but there's no way to know without datalogging. Fight for your tuner's attention, it could be what saves this engine in the rare event that something IS wrong and you can't tell (fuel trims way lean due to slight exhaust leak at header for example)

I am going to wait for his reply for another day or two and see what happens. If don’t hear back I am just going to go to local tuner.

the answer will be that you can drive
you haven t change anything technically
and if you want you xan post a log here you have to do it anyway, just drive gently
