hay guys,

installed my LTX12 in my car other day and tryed to start it today.

i put it in test mode and u can hear the injectors working, i took a plug out to see if i got spark, and didnt.

Any one got ne ideas on how to fix this?

i tested the cas to see if it was wired up right.

i got 12v on red black was ground, and 2 other wires i got 4.9v's i hope this is correct.

so if cas has power and signal why dont i have spark?

also the ecu came out of a rb26, is there ne thing i need to change in settings?

Cheers

Justin

i got no idea about ne of that. i just thought it should be ok just to make it start make sure it runs then send car of to tuners and they can adjust all that stuff.

so as the cas is different does that mean i gotta send ecu to microtech to get them to change the settings on it?

its not just the CAS

the whole program needs to be reflashed to suit RB25 microtech charge about $300

what a load of crap^^^

I rewired a microtech from a ford v8 with electronic ignition to a turbo ford 6 cylinder with hall effect ignition rang domenic from microtech he told me to make 2 changes and the car fired up

i would recomend you take it to someone who knows microtech computers

adriano is probably correct bt saying dwell is incorrect as i was running cdi ignition. It could also be a different setting for the cas referene with r34 cas

any troubles with microtech they also hace a tech help line

cheers Jason

well thats what i got told from microtech when i got my one reprogrammed

Thats what i was wondering. Ive never had any luck with calling microtech, when they finally answer the phone, they tell you to bring it in for reprogramming.

thats exactly what i get told every time

but apparently im full of shit ROFLMAO

    • Thread bump, again! Although, no bad news this time. Posting for the sake of possible root cause. Basically, I rebuilt it (mostly stock), installed Haltech + sensors, had it running fine on new ECU.  Still not really understanding why it cracked pistons last time. Got to tuners, and while checking timing, noticed +-10deg of timing scatter while revving. Changed CAS, and it was rock solid. While not definitive, can't imagine seeing 20+ psi with that amount of scatter would be a good thing. Also glad I found something.   Bit more of a run down; Carried out a stock rebuild, a set of stock pistons, out of a spare bottom end. Everything stock apart from head studs and oil restrictors. (so I can pretend I didn't let the Nissan out, ha.) Armed with the measuring gear and FSM, set about doing overhaul. Oil restrictors as per oil control thread for a RB25, stock oil pump, drifting. Head drain/vent from rear of head, to passenger side of sump above oil level. Two dash 10 vent lines from drivers side of sump (unused atm) Hi octane style cam cover breather kit Splash covers over last 2 cam caps. Both breather lines from cam covers to vented to atmosphere catch can, not plumbed back into sump (wanted to see what it was actually breathing). Got it run in (did about a 1000km) no to low boost scenario, As I had questions over old ECU setup. Installed haltech +sensors for flex Retune on E85 (finding CAS Issue along the way), made 300rwkw at 20psi, out of wastegate. Did a drift day the next day (yes, it was a big weekend!) and was checking catch can throughout the day, ZERO blowby. I mean nothing. Lines from cam covers are not even wet. Done a bunch of street driving, spirited and catch can is still dry. Early days I guess, but pretty happy so far. Also now run 10w60, up from the 10w40 that I used to run. Oil pressure is significantly better, especially when hot (as you would expect)      
    • Thanks buddy. I thought it was a server storage thing. 馃ぃ
    • Perfect! Thanks for this, both look like great options!
