ECU socketing $60 .. to upgrade your ECU your ECU must be socketed if it is a 90-94 TT ECU.. Over the years we've seen many ECU's destroyed by individuals who want to do it themselves.. I'm a DIY'er and have found on the older Z's now it is very difficult to remove the oem chip without professional equipment and know how else it's damaged and unprepairable in most cases.
ECU eprom upgrades from 90-94 a simple eprom upgrade can change all of your maps timing rpm limiter mph limiter .. making it safer to run higher boost. Others charge up to $500 and some as little as $100 But we're still at $60
ECU upgrades for 16 Bit ECU's ..$399 Our 16 bit upgrade contains something that puts us far ahead of the others .. Nistune daughterboard.. With others you can not change anything....non upgradable unless you buy a completely new PCB and have it installed
Socketed ECUs .. $160 We also keep a spare or two around and that's what other Z owners are doing now.. In the last year we've seen more than a few ECU's that have had injector circuit failure..
