I rebased Shiv’s E85 EL tune off of Wayno’s v85 E85 tune and combined the performance improvements of both. It works better on my car using the
Pearson Fuels E85 in my area vs Shiv’s or Wayno’s tune.
I present to you the culmination of my work. I see a huge difference compared to the OTS E85 tune or Wayno’s v85 E85 tune. Wayno’s tune is awesome and this tune would not be possible without it.
It has provided an excellent base from which to make tunes like this. Wayno does provide an E85 tune, but it is tuned to Australian E85 which may or not be worse than US E85. Wano's tune has more relaxed timing vs my tune. What I have done is use Shiv’s more aggressive timing except in cases where Wayno’s was more aggressive. After finely tuning the tables the result is not only a tune that has more advanced timing than both, but also a tune that has been proven by both.
This is the best feeling tune I have ever used. I’ll admit I haven’t put the car on a dyno, but the increases in power and drivability are obvious.
This tune is optimized for USDM vehicles on US Pearson Fuels E85. My car is an AT A01D so that is what my tune will be coming in. It is easy to copy the tables to your specific ROM type yourself. Just make sure you start with Shiv’s OTS 2.x Stg 2 EL E85 tune.
If you have any trouble copying over tables look at Wayno’s
thread.
Keep in mind this tune is for Automatics. You should already be familiar with Wayno’s tunes before using this tune, unless you just happen to have a A01D, in which case flash away.
This tune also works well on a stock car.
THIS TUNE WORKS GREAT FOR MY VEHICLE. I MAKE NO GUARANTEES THAT YOU WILL HAVE THE SAME RESULT.
THIS TUNE IS NOT IN ANY WAY ENDORSED BY WAYNO OR SHIV. YOU AGREE TO FLASH THIS TUNE AT YOUR OWN RISK AND WILL NOT HOLD ME, WAYNO, SHIV, OR ANYONE ELSE RESPONSIBLE FOR ANYTHING THAT HAPPENS GOOD OR BAD AS A RESULT OF USING THIS TUNE. FOR ADVANCED USERS ONLY.
This E85 Tune features:
- P0420 removed.
- Rescaled O2 sensor from 12 down to 10.5 - thanks to ztan.
- Quiet cold start - thanks to steve99.
- Knock prevention for high coolant temps - thanks to steve99.
- Radiator fan activation when car is at operating temperature and under 70kph. This maintains coolant temp and keeps the engine bay vented down the transmission tunnel and past the steering arms at low speeds, preventing heat-soak. - thanks to Wayno
- Custom cranking tables. - thanks to Wayno.
- Fuel display updated for E85. - thanks to Td-d.
- Custom load limits. - thanks to Wayno.
- Custom MAF Scales. - thanks to Wayno.
- Replaced throttle map. - thanks to Wayno's base. Customized by me.
- Soft 7550rpm rev limit.
- Advanced Timings for USDM Pearson Fuels E85.
