ToddLS400 Posted May 7, 2003 Share Posted May 7, 2003 Is there an aftermarket computer chip (Dinan?) for my '90 LS400? If so, how much more horsepower do you get? Quote Link to comment Share on other sites More sharing options...
ToddLS400 Posted May 11, 2003 Author Share Posted May 11, 2003 http://www.speedfreaksspeedshop.com/en-us/...s/dept_966.html I found these JET ECU upgrades. It just doesn't seem very specific. It just says LEXUS (all models). Does anybody know of somebody that has used this? Quote Link to comment Share on other sites More sharing options...

ToddLS400 Posted May 19, 2003 Author Share Posted May 19, 2003 $1,249 for 30HP? What? That isn't worth it. I would rather pay for headers or do the twin turbo upgrade for a little more. The TT upgrade gives you over 100HP more> http://www.lextreme.com/TT-System.htm Thanks for the info....If it was around $500 then that would make sense... Dyno Results 5/7/02 +30 HP +50 lbs Torque Dyno Facts: 1. The Dyno runs were done on the SAME DAY, SAME CAR, SAME TIME, SAME MACHINE, SAME DRIVER, SAME ENGINE TEMP, SAME ATMOSPHERE, ETC. 2. There were NO changes in our computer versus the one we sell. 3. The program we use is for street use, daily drivers, VERY SAFE & POWERFUL. 4. The dyno shop is well known and very reputable (*Sport Compact Car Magazine uses this company for their project cars.). Owner: Darren, R & D Dyno, Gardena Blvd. Carson, CA 90745, (310) 516-1003. 5. The test car only had a Rod Millen Muffler system, no cat-back. 6. All results are horsepower and torque at the wheels. 7. WE GUARANTEE OUR RESULTS! All data is direct from the shop to you. Dyno Summary: 1. In the first graph you can see that the Horsepower & Torque increase through the ENTIRE POWERBAND, not just at certain points. You do not loose anywhere, only gains! 2. In the numbers section the left side is the stock ECU and the right is the LexusSC400.com ECU. 3. Notice at 6000 RPM on the stock run the horsepower is 116.9 corrected. On the LexusSC400.com run the horsepower was 146.2 giving us a gain of +30 Horsepower. This was done in 1st gear, 2nd and 3rd were much higher. 4. Notice at 1750 RPM on the stock run the torque is 80.9 corrected. On the LexusSC400.com run the torque was 130.9 giving us a gain of +50 lbs of Torque. This was done in 1st gear, 2nd and 3rd were much higher. 5. You gain power throughout the entire powerband RELIABLY & SAFELY! Quote Link to comment Share on other sites More sharing options...
