Next up some cleaning up.

Quite possibly the most requested product after initially making a few of these 5afe/4afe/7afe plug and play ecus a few years ago. On average 5-10 DM or emails per week for these.

We are happy to announce that these will go back into production in the month of May and will be available soon after. They will be built per order.

100% standalone ecu for your 4a/5a/7a project to replace your 30 year old ecu with a modern programmable ECU. Whether your have a 100% stock motor or building a turbo monster this is for.

Stay tuned.

Last but certainly not least on our Dominica trip, Sherman's Subaru STI hatch. I originally tuned this car a few years ago and we stopped at 600+ whp after maxing out the map sensor.

New setup consists of 68mm turbo, 5 bar map sensor, system and every supporting part you can dream of. Still awaiting a few tiny bits, but definitely one to look out for once completely.

Recap of Lime Em Up Racing over in Dominica with subaru wrx.

Day 1 - test n tune - focus was to clean up low boost map and to have some 11 second A to B passes in the bag. Closed off the day with 11.8 ¼ passes with plenty left on tap. Overall happy for an unprepped surface.

Day 2 - raceday - goal was to turn up power and better our 11.5 ¼ PB and go for a 10.9x ¼ mile on higher boost and race gas, as the data indicated that it was within reach on a perfect pass.

1st full pass of the day was elimination run against Toyota celica, a highly anticipated race. Everything that could go wrong, did go wrong during that pass. Horrible 1.97 60ft, missed 3rd gear and only managed a 12.47 ¼ mile. That put us out of competition.

Lots of takeaways from the weekend, however we will take a not so good day at the track over anything else.

Looking forward to the next version of this car and getting that 10 second monkey off our shoulders.

Thanks to all who made the weekend memorable on and off the track.

Thanks and team for intense racing. Thanks and all who worked hard to put on a great event.

Dominica. I will be back.
