Re: Which forged pistons to make my ka-e 8.6:1 comp ratio
IIRC, the de has a 45cc combustion chamber vs the e’s 65cc combustion chamber. There are a lot of variables that will effect your compression ratio: bore, stroke, head volume, head gasket thickness, how far the head and block have been decked, piston dish, etc. I’d recommend google searching “compre...

Re: 93 boosted 4x4 hb tune questions
Post your .msq or a screenshot of your ignition wheel decoder settings. Is your wheel the new 24-2 or the old style dual 12-1 with the single separate cam angle tooth?

Re: GTX3576R .83AR too big?
A good rule of thumb for sizing a turbo for a street car is to use the smallest turbo that'll hit your max power goal (while still in a good efficiency zone for the compressor). That way you make the power you want while sacrificing the least amount of response possible. The GTX3576 is rated for 750...

Re: Spun Bearing Questions
Unfortunately, it's hard to pin down a definite cause until you pull the motor apart. My guess would be inadequate oil pressure, severe oil contamination(metal, dirt or fuel) or error in assembly. From personal experience, I can tell you it takes quite a bit to spin a bearing in these motors. When I...

Re: Wild afr fluctuations at WOT
Alright, I've had the tuck apart for almost a month, I figure it's about time for an update. (Buckle up, its gonna be a long one) So the sensor responsible for measuring the AFR content of your exhaust gas is fluctuating.....but you have ruled out the exhaust gas leak pre turbo/pre afr sensor as the...

Wild afr fluctuations at WOT
Over the last 2 years I've been fighting an uphill battle trying to maintain a stable afr at wot. I've read every post on every forum on the subject, or related subjects, but the (not quite) infinite knowledge of the internet has not rendered a solution. I've replaced my wideband gauge and sensor th...

Re: Hitting a wall at 4500rpm
What is your coil dwell time set to? Every time I've experienced higher rpm cutout, it's been due to too high of a dwell value. Stock coil seems to like 3.0 ms.

Re: Megasquirt MS3X KA24DE wont start
I'm not seeing any spark advance or a timing table in the logs, do you have an ignition advance table set up? Also, double check under 'Ignition' > 'decoder wheel settings' and make sure its not set to fixed timing at 0 deg advance. Thats my best guess until you post an MSQ file.
