that's easy, because it's not reading the sensor.

I unplugged the sensor and it dropped to -40(ish, IIRC). Bad sensor? Dunno, wrong thread, my bad.

mm treadstone. I have a treadstone core in my v8 wagon, it does well but it's also a bit small (hindsight and what not), it still doesn't get really super hot. The ebay intercoolers seem to be more along the lines of about 3/4 what they're rated at, whereas the garret/treadstone/precision cores seem to be a little bit under rated.

So I managed to find another L33 in the junkyard. $120 for a complete shortblock L33. No real changes this time around besides switching to the "dumb" coils and upgrading the intercooler.

My buddy that runs a speedshop was able to get me a TR1245 Treadstone core at cost so I bit the bullet and purchased it. Can't wait to see this work of art in person. Going to need to cut a good amount out of the core support to make it fit but I'm going to do my best to get it to fit.

I've heard two different sides to the random discharge story. What's your dwell set at in the ecu? what's it saying in the datalogs going down the track?

3.5ms and a 1ms spark duration. I think they might have been getting weak and letting go early when they were approaching 4.5ms total time.

I also noticed on the batt voltage compensation it was adding 4% dwell between 13.3 and 12.0v

A few things combined may have lead to this in the ignition coils.

Love this car and the simplicity behind it. Can't wait to see that monster of an intercooler.

Thanks. Me too! I'd love to stop fixing the damn thing at this point haha. Hopefully this time I can enjoy it for the next 4 or 5 months before I go back overseas. Really dont want it to break again so I probly won't be putting it back in the 9's this year.

That's understandable, definitely need to enjoy it while you can. Are you PCSing or deploying?

drop your dwell to 3 and discharge time to like .5
I'm not really convinced that was your issue though, a lot of the guys that really had problems with it were running much higher dwell

I agree for sure that these aren't aggressive settings by any means really. The main reason I'm suspect of them is because my last set of d585 coils, 367k miles, prior to this worked flawlessly and as soon as I switched to this set, 220k miles, that came with the damaged L33. I've had ignition issues almost the entire time with those coils. Mainly under bigger boost numbers, 18+ psi. Problems I never had with the original set of d585 coils.

Plan moving forward is to install the set of square truck coils I got from 73amc in exchange for my heat sink coils. Gonna turn up the dwell to 4.0ms and leave the 1.0ms ignition time. My thinking for that is the square coils are weaker but won't self discharge so I will try and make up the ignition energy with a SLIGHTLY longer dwell period than the d585 coils had. I think 4ms is still well within the realm of a safe dwell period. I've read about max effective dwell being around 4.8ish ms. Over that there wasn't a measurable increase in spark energy.

I am curious as to the rational of dropping the discharge time from 1.0ms to 0.5ms? Honestly interested in the reason there.

I'll have to dig around and look, I forget why the discharge time is even really an option, it had something to do with older coils iirc

I wonder if new coils like the square truck coils need that much or if they fire fast? Interesting for sure.

Got the new intercooler in with some trimming. Decent option for the high powered redblocks/whiteblocks/LS's out there if you don't want to move the radiator or intercooler location.








Also had a final message for the engine before I set it in its new home lol

Had a weird feeling about the injectors so I sent them off to Eric Derr to get flow tested and cleaned. $75 for 8 tested, cleaned and shipped back. $115 for 16. He does excellent, fast work.

I'll post up the flow sheet of the Bosch 210's and any photos if he sends them. Injectors should get to him on Wednesday and hopefully I can them back this weekend or maybe Monday/Tuesday. We'll see.
