Hondata S300, worth doing?!

[IV73CI]

Ebay ones see shit and some still need extra wiring el cheapo harness.

Buy Rywire or something along the 100$ + range and it will be a better quality and will actualy work.

He means, ECU OBD2A to OBD1 conversion harness, its like 60 bucks on ebay shipped from the states, or $100 bucks locally used

Oh yeah, $100 is fine but I'm thinking in my head no way would this be a PITA like going OBD0 to OBD1 lol. Much easier the other way round...

you need to find a dealer in Australia to purchase Hondata now by the way...

I have found a Ecu on ebay called the ''Black Ecu'', Hondata s300 installed and is from the states!

Sorry i meant verson 2, which just got released. Let me know how it is

I purchased my S300 from the US as a complete unit with OBD2A. About $830 shipped. Keep your old ECU in the cupboard in case you need to return to stock for whatever reason / selling / etc.

My car made 125kW atw with Toda header, high-flow cat, RM01A and Mugen intake. With S300 tuned by Adrian @ Toda, it made 135.6kW atw. Noticable gains in the midrange, much smoother VTEC transition, definitely well worth the $$ spent. I regret not doing it ages ago.

The key is in the tune though... an experienced tuner will make your car reliable and economical on cruise, not just focus on dyno numbers.

Dyno chart before & after ....

Torque before VTEC now the same or better than in VTEC before (bottom lines).

Notably smoother - check out the VTEC transition.

Worth it? I think this graph says it all, but driving it is even better.

Awesome results. So what was ur VTEC point moved too? I can see you have gained a fair bit of mid range...how long did the tune take?

Yes the midrange is definitely noticable from the drivers seat. Especially accelerating in 4th and 5th, you don't need to downshift as often in traffic/overtaking etc. VTEC engages at 5400 with full throttle, up to 5700rpm with part throttle (VTEC engagement window).

Time spent on the dyno around 4 hours plus miscellaneous time for setting up etc.

Nice!!, I heard alot of good things about Toda and there tuning.. How much did that cost you?

[u mad?]

135 with bolt-ons and tune

very healthy number!

Which spark plugs did you use? Any idea? I heard hondata recommend using resistor spark plugs with non resistor spark plug wires
