Plug and Play ECU
|
seems really expensive why not just run 2 ecus
|
No chopping the harness, and it's in the low mid range price of any other standalone that would require hacking the harness. What's a cheaper option besides MegaSquirt?
|
Haltech $2000 for standalone and adapter harness. Basically what I was saying is why not just use the stock ecu to control what the stock ecu wants?

The only reason to keep the stock ECU in a high power application is to run the gauges. With this, you don't need it at all, con't need to find space for another ECU box, and it's $400 cheaper than the Haltech. Plus, if you can control the gauges with the new ECU, you can program them to do whatever you want. Change the MPG gauge into a boost gauge. It's a well known system down in Australia and New Zealand. There is a tuner not far from me that uses them in Supra's and RX7's that can tune it, I was hoping to see someone with a Lexus that has installed it and done a write up.

Be sure to pb blaster the rusty bolts and let it sit a minute. Northern cars are bad with rust. I don't think I've seen a IS with that much rust under it but pretty color bro. Keep us updated

Heres why 2 ecu haltech is a better idea (or any other brand dual ecu) 1. You’re wrong the stock ecu controls way more than you think. Including(what I’ve heard) windows, locks, pretty much anything that makes the car a streetable car. Look up canbus I think that’s what the wiring style is called. Basically it’s 1 computer that controls all the systems. Instead of separate computers for each 2. haltech has more tuners that are familiar with it. And haltech is a reputable brand. 3. Haltech makes all the harnesses to plug and play with 2 ecus |
I'm well aware of what CANbus is. 2 ecu's and a modded harness is more points for failure, and the haltech is between $500 and $1000 more. I personally have 4 link tuners within 100 miles.
But I didn't start the thread to become a pissing match between brands, I was curious to see if anyone had actual experience here in the states with an IS. |
