These assemblies from Jason Waters Tuning utilize a Xenocron-type design with authentic GLS27SF512 chips which are many-times-programmable as SST27SF512 using the BURN2 and other programmers. PLEASE NOTE that these particular modules do NOT have A15 connected, so they are essentially 32k chips with addressing from 0000-7FFF. This is fine

Thumbs Up

Working great with my 1987 GMC Pickup. Along with the G2 Adapter.

Like the SST chip, but better!

The JWT chip works fantastic in replacing the old SST chips that seem to be running out. Loading tunes works the same as they used to. However, these chips aren't notched to know which is the correct direction to socket them in, recommend marking which way is "up".
