Hard To Handle Mr30?

Hi

I have a Mr30 with a Rb25det etc R200 diff with a detroit lokka in it and its the hardest car I have owned to keep under control in a slide.

Is it the diff or suspension or just thats what 30s do?

I have replaced all the rubbers in the rear Koni shocks in the rear set near hard. I have a S13 front end to install and coil overs all-round I hope this helps as it feels like the car is out to get me every time I put it in a slide.

Its possible I have just lost my talent but I'm hoping not.

Any advice etc would be appreciated

Steve

Double check your alignment, front and rear.

Detroits have particular drive characteristics. That would be a factor - do you know how they actually work, and what to expect from one as you power on and then modulate the power?

Also how much steering angle is available in a MR30 front end?

If u been driving silvias all ur life then yea bit different. Lol i found mine when i had the 25 in it waz awsome.it loved it. Diff plays a major part so may take a bit of getting used to.

I found when i had mine with the rb20 it was like a lead tipped arrow. very hard to keep balanced and most of the time its ass would swing out way too far.

problem is that the rb is very heavy on the front so you need a good suspension set up to make it handle best.

I had stiff konis and kings in the rear but 90/10's on the front wich was half my problem. perfect for drags and high speed freeway but try and drift it and was

usually 90 degrees+ to the footpath followed by slamming on the brakes.

so the s13 coilover option with a proper spring rate will help you out.

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).

      ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
