Help!!! ISF is redlining @7200rpm!?!?
Help! Wierd things are happening ever since I installed the contents of a package which contained a "mysterious" performance part from Japan.
Here's a video of it happening
YES, I know!! Too much wheel slippage. Well guess what those 275 rears are working A Lot harder now to not break traction and so am I (I haven't gotten the "touch" just right yet) And the rev limiter bouncing was intentional to show actual redline.

Less than stainless coated Ppe headers high flow cats and labor to install (which was the other path I was looking at).
To be completely honest, I don't think I'm gonna go that route anymore.
This was WAY MORE than expected, or quoted to me by novel. Promised
Me
20 Whp , 30 lb/ft torque.
Said only any mods would "enhance" result and that the higher the octane I could feed it would also "enhance" result.
On MY car, with 96 octane (super 93 + Royal Purple +3 = 96)
I'm getting
+46 Whp
+50 Lb/ft Torque
(Unverified by dyno)
Dyno before ECU mod had me 354whp
325 Lb/ft Tq.
Can only go by what dash command and tire slip are telling me right now.
DC eng power B4 436 hp now 494 hp
DC eng Tq B4 369 now 416 (scratch that last run was 428 see later post pic)
Yes above is ENGINE NOT WHEEL.
My dyno showed approx 81.4% driveline efficiency.
Post mod dyno two weeks out but...
When I had 225/40 f 255/35 r had lots of traction limiting events at wot 1-2 2-3 shifts in manual mode.
Largely gone when I went to 255/35 f 275/30 r,
Well...

Get you all hard dyno numbers as soon as I get em.

Sounds very good!
Would you mind sending the dyno results when you have the chance?
Thank you very much!

Rev. limit up to 7,200rpm
Speed limit up to 320km/h (approx. 200 mile/h)
We provide the tune in a replacement EUC. The installation is simply, just remove the stock EUC and plug our ECU as the stock is connected.
We don’t think that your already exhaust system and other changes would cause a problem on the ECU. But it is recommended to set up the ECU with physical car in order to maximize the ECU tuning.
We will provide you the result of our dyno check shortly.

I accept your cautions on fuel and the possibility that there could be issues that are outside of your control. I have 93 octane where I live and use that exclusively.
I wanted to check a couple of things.
Does the ecu raise the rev limit on the car and remove the speed limiter? Also do you have a dyno chart example that I could look at? I already have aftermarket dual exhaust, and would like to add headers, intake , and throttle controller, would any of these pose a problem with the new ecu? Do I have to supply my own ecu to get flashed or do you send me a replacment unit? Finally how difficult is installation and where can I obtain instructions?
Thank you for your help. I look forward to getting the details above because I would love to have this running in my ISF.
Respectfully, Jamal Tabeb

Hello Mr. Jamal Tabeb
Thank you for your email.
EUC tuning has been confirmed on a LHD ISF imported from US with Japan regular gasoline (92-96 octane level). Approximately 20hp of power gain. However, since actual compatibility with US gasoline and under climate in US is not taken, it could be a possibility that trouble occurs.
If you can understand that there is a possibility that a problem could occurs, the EUC tune on a new EUC is available for sale at JPY 300,000. + Shipping to your place (should be below 50USD)
Should you have any question on above or our other product, please do not hesitate to contact us.

hello was just wondering if the Lexus IsF ECU tune was available for purchase in the USDM and not just in Japan?
I have a 2010 with headers and exhaust from after market, rest is stock.
Thank you!
