Injector & ignition pulse simulation
Power, ground, and load-circuit analysis
Flash memory integrity and checksum validation

I recently purchased the 89661-17690 ECM for my 2004 Toyota MR2 Spyder, and I’m really impressed with the whole experience. The unit arrived quickly, and the shipping cost was very reasonable, which was a nice surprise. What stood out most was the plug-and-play setup—they had it pre-programmed for my VIN so installation was straightforward and hassle-free. The engine has been running smoothly since I installed it, and I’m glad I found a seller who took the time to ensure everything was ready to go. Definitely a reliable source for anyone needing an ECU replacement.
