it runs... It runs...RB26 and Mircotech

Well the long awaited moment has happened. The engine cranked and fired. :cool: that is the good part.

 

I am hoping someone out there can help with offering advise on tuning the Microtech LT12S. I adjusted the TPS and timing and they seem fine now. Engine runs much smoother.

 

But man is it rich.... 650cc injectors and everything is black. Now I read good things about Microtech - and I purchased the LT12S, iginition pack and their wide band O2. What I find they are lacking is some basic tuning instructions.

 

I don't have the hand held controller - but the laptop dongle interconnect.

 

Things I notice that I find odd

 

- the timing curve (map) jumps up to 30 by 2000 RPM - what should the timing curve of the RB26 look like?

- the injector map - is flat and set at 0%. I am open to suggestions here, or a screen image.

 

what is the difference between Matrix and Normal modes?

 

Things left to do...

 

exhaust, guages, get the alternator charging, 300 ZXT half shafts installed..... and tune.

small update...

 

no further tuning has happened although the exhaust system has been completed. I also ended up getting the billet CV adapters from Modern Motorsports vs. the welded units - I must say Ross was very quick to respond and ship the billet peices when I found a challenge with the welded adapters - thumbs up to Ross:icon14:

 

Other challenges - some soft frame rail that is being repaired right now. I was a little supprized - I found this when installing the adjustable TC rods. Will be better than new now!

 

Reversed the races in the CV joints and tore a boot - ordered new boots and they should be together this week.

 

have to install some guages - boost, fuel pressure and a second oil pressure guage. I bought two sending units for my Ultra Light oil pressure guage and will wire it up to switch between fuel and oil.

 

Also have to install the boost controller - picked up the turbonetics manual boost controller for mounting in the cabin - this could be dangerous!

 

i hope to go to the strip on Saturday for a test run. I thought i would have the car on the road before it snowed here! Well i missed that when it snowed this week - unusual for Toronto. Cold air is dense though.....

 

update next week
