6G Celicas Forums

Thanks. Pinging pretty much gone now, I took out base timing by rotating distributor. Where I was wrong is not thinking about what the stock ECU is seeing, and how it reacts under this condition.

If you have a 3S-GTE why would you run a 5SFTE? The 3SGTE would make more power? I only turboed the 5S because it was cheaper than a 3SGTE and I was not chasing big power.

I originally had supra NA injectors (360cc?), these were logging 90% duty cycle so I changed them for the RX7 injectors, but it runs rougher at idle and low speeds with the bigger injectors, harder to get the tune right.

Wanting other peoples advice for my 5SFTE that I've just got going. Curious to know what sort of timing curve people run, I use a Emanage so it is a correction map rather than a timing map. Running stock fuel pressure regulator because I can't understand why most people use an after market one, maybe someone can enlighten me? The engine pings under boost yet I have pulled the timing back 13 degrees and see a AF ratio of 12 on the AEM wideband gauge. I run 98RON fuel. It is in a ST204 celica.

Also curious to know what plugs and plug gaps people run in such a motor. I've got copper in a NGK 7 heat range, gapped to 0.028"

Had a misfire under boost, changing the leads (which were near 10 years old) fixed this.

If anyone wants my experience on this to date I'm happy to share.
