FrankenSpeed Strikes Again

Here we go again my friends, with yet another installment of MazdaSleeze..
So, on today's episode we are discussing why my '12 MS3 is against me.
So for those of you who haven't seen my previous posts, nor care to dig, I bought a '12 MS3 that was fully loaded with no knowledge of what I was actually getting into.. here's a modlist
FMIC swap
VTA BOV
3" HTP inlet with stock MAF
3.5 BAR CS MAPsensor
Autotech HPFP internals
PCV delete on Intake Manifold for OCC(unfinished)
as far as I've been able to tell, that's all there is
now THE PROBLEMS
The car is currently parked and has been for the past several weeks as a tuner buddy of mine has been helping me try to dial in the MAP/MAF calibrations. The car will not hold idle, we thought it was the calibrations being so far off due to having to delete the tune that the previous owner had on it because of VT deleting all the logs I had before. All my fuel checks are good from what I can tell, the engine fires but it refuses to hold an idle. I have KOEO logs as well as attempts at starting. The car ran before I parked it but had terrible issues with dropping into limp mode randomly... We need some serious help, any suggestions are greatly appreciated. I'm not 1 for quitting but this is becoming a gigantic issue for me..

 

Have you tried a different MAP sensor? The CS ones have been known to fail and that would definitely make the car unhappy.

 

Have they? We thought we'd try different values to try and make the sensor read at a 3 BAR setting. i did order a Bosch 3 BAR, just isn't here yet. KOEO logs have the map registering at 2.03V. that just doesn't make sense to me unless it's either a wiring issue, or ya i guess the map sensor itself.

 

Get a protuner. In the past 14 years of owning a speed, we've seen buddies blow up or jack up the tune of a car countless times. That may mean well, but this may be why

 

well, I say tuner buddy but he's a lead tuner at his company. May not be on the VT etuner list but he's very knowledgeable and attentive

 

Ok so quite a bit has happened as of late, I apologise but I was never good at keeping a diary. SO, my tuning is going well, on my 5th revision so far. But I've been keeping a close eye on my occ because I've noticed it collecting quite a bit of fluids lately. Ram a compression test 185/180/115/165. Now cylinder 1 was a bit oily so I definitely need a new valve cover gasket, but cylinder 3 is poop. I'm pretty sure I'm either looking at injector seals or ringland failure of some kind. Any suggestions?

 

Injector seals, valve cleaning. Then compression test. Get injectors cleaned too.

 

Ya, seals are definitely on the list. Is there a thread on here comparing brands by chance?

 

CS or Overspeed, pick your preference

 

Really, I figured Damon would have something

 

So I've had luck with using seafoam for cleaning valves in the past. What're your preferences or methods?

 

Not that. I'm using chemtool B12 to soak. Corksport blaster kit to clean. Check my Neverending love/hate thread.

 

This is exactly what everyone says right before they blow up

 

Well honestly, with the state of what I've seen from this motor in not really trying to go for much more than stock until I can save up to get some beefy internals. Turns out I've got low compression in cylinder 3 anyway (115) so probably gonna rebuild cpe/manley pistons anyway

 

Do you plan on building next week?

 

Not exactly, do you think I have no more than a week?

 

Depends on whether or not you have taken the advice about your tuner buddy

 

Well I've kinda stopped the tuning process once I learned about my compression issues. I'm not stupid
