Default 20022006 Lexus ES300 ES330 other models factory transmission/accel "Lag fix"

Please don't flag this post. I am new to club lexus. to get help and help out. Not for Sale ad

*****Update August 20, 2017: Holding down (-) button puts module in Auto mode, display shows "AAA" and holding down (+) puts Manual mode, display shows "SSS"

Note: For 2002-2006 Lexus ES, I noticed put Mode P2.1 then hold down (+) to show "SSS". This setting works best for 2002-2006 Lexus Es300 Es330


How to fix 2002–2006 Lexus ES300 ES330 other models factory transmission/acceleration Lag fix:

Starting in 2002 Toyota Lexus started to switch to "drive by wire" system on its cars. The accelerator/gas pedal became sensor that sends digital signal to ECM and then ECM controls other functions based on that like how fast and how wide the throttle opens and transmission shifting. In early design like 2002-2006 es300 es330 camry others,Toyota simply took its old TPS sensor that were mounted on throttle bodies and placed it on accelerator pedal. From factory this sensor was set to give slow reading to ECM, not sufficient for drive by wire system. Current Updated Accelerator pedals use magnetic sensor on pedal and driver is given option buttons on dashboard like ECO, SPORT, Normal etc. to tune the ecm. On older gen. like 2002-2006 Es300 330 customers right away and to this day notice LAG/Unresponsive acceleration and gear shifting. "speedkar99" youtuber called this phenomenon the "lag tard" on club Lexus. When I got my 2005 Lexus Es330 in San Jose, California as used car, I also noticed this lag in acceleration and weird transmission as many others complaint same. I did many things like change accelerator pedal, full tune up, transmission fluid flushes and reset ecm. All these helped but not fix factory design problem, the pedal sensor is too slow to give reading to ecm. Last solution: I always wanted to try the throttle controller modules that plug into pedal sensor like Buddy Club: http://www.buddyclubuk.com/acatalog/BC-ETB-FN-FD2.jpg and apexi, sprint booster etc. but they were too expensive for my budget. One day, I went on alibaba.com and chat with seller in china that sells "9-drive throttle controller" ask me for seller if needed. I sent them photo of my 2005 Lexus es330 accelerator pedal connector photo: https://ae01.alicdn.com/kf/HTB1wvq9O...-Connector.jpg and paid on paypal and seller ship me 9-drive controller from hong kong to San Jose, California in 3-4 days DHL.

Unit price: $45/pc.

Shipping cost: $19by DHL within 3-5 working days you will received.

Paypal fee: $2.82

Total price: $66.82

***unit price can be negotiated to $35 I think***

I simply plug n play the module on accelerator pedal. They send you the correct connector based on your car. There are various models out of china/hong kong. After the install my Lexus "WAKE UP" after many years. I can put it in Eco, Normal(factory), Normal + , sport, race modes. In each mode you can pick 9 levels thus 9-drive. You plug in small module on pedal sensor then install tiny controller on dashboard. I put my es330 on P2.1 which is sport begin mode and my lexus response to tiny touch on pedal. THE CAR JUST WAKE UP and drives like new with no lag. In eco mode the rpm move very slow in response to pedal and in sport rpm move right way to pedal movement thus no lag. U can put it in nor/factory mode also just with touch of button. The module tunes reading coming out of pedal sensor. No more, when you press pedal and ecm thinks what should I do and then responds. I been using this for while and No check engine light. I highly recommend throttle booster/controller for cars after you have tried everything else like me. Please look for sport, eco, normal buttons on newer model cars on dashboard. ASK ME A QUESTION FOR ADDITIONAL INFO. email: [email protected]

Interesting. Do you feel a pretty big difference compared to stock? How about between mode 1 and mode 9?

Default Yes, big response, no lag

Answer: yes there is pretty big difference.

Modes:

Nor = factory setting

EC = Economy 1thru 9 levels. rpm move very slow in response to pedal. Worse than factory response/more lag

P1.1 they call it comfort mode, I call it Normal plus mode. I like P1.5 setting as it is step up from factory mode. This has 1 thru 9 levels also. Least to most responsive

P2.1 Sport mode with 1 thru 9 levels. Quick acceleration

P3.1 Race mode 1 thru 9 levels. Rpm hits 4,000 with just pedal touch to race
