Exclamation Having trouble starting car. Map posted

Always had a bit of trouble starting my car. But since installing new rear muffler have only been able to star once. Tried all the usual. Pull the plugs and deflood, replace plugs with new ones. Not having a lot of luck. Car hasn't seen a lot of time on the road, so replaced oil and petrol as a precaution.



FD , rebuilt engine, all new parts, less than 200km on the engine, full bridge including the centreplate, single turbo, 3" exhaust into a 2.5" adrenaline R muffler on the end, microtech Lt10 with the microtech ignition box. All standard injectors 550 pri by 850 sec??

Had it tuned after rebuild by RX7 heaven in Auckland. Tony started it no worries when I went to pick it up. I flooded it when I next tried to start it and it has always been hard to start since. Have tinkered with the crank map without much luck (temps are around 18C in NZ at the mo.), but it had an injector output of 12 when I started anyway.

Have Ls1 wideband.

Have removed intank pump, installed external 500Hp, upsized line to 9An I think to FPR set at 40psi. WG spring is 12psi.

50+ views and 1 reply. Cheers arran. Have looked up a heap of maps, but havn't found any referring to a bridgeport on stock injectors. Going to max out my injector outputs today and have a dig around in there. Will post how I go.

Update

Proved spark, looks good will jump 10mm no worries. I see someone else soaked their injectors in degreaser, so tried that for two hours flushed them and then tested them incar. Both spray the required mls & spray pattern sweet but one doesn't shut down when powered down..comes out like a **** for about five seconds then drips..
Probably explains why I have been able to fire up one rotor. Wish I had checked the injectors before I soaked them. Will post a couple of photos for laughs. Ordered a couple off trademe for $70.

Injector failures are very, very common. Practically every car I run into has a bad injector.

Generally you can have them cleaned at a local injection shop for a few bucks. I just had the 3 injectors in my Insight done for $30.

Bridgeports need a LOT of fuel at zero vacuum conditions to get going, so you may find you need 2x to 3x the amount of fuel you think you do to start the engine.

So have a look at this

Not sure if that uploaded or not. For those with microtech, change the file extension back to .mtl format and have alook. For some reasondespite having RPMmap set to 3000 and the other set to 00psi my outputs are in sT from the get go. Any ideas, honestly I'm thinking of defecting to a haltech pro sport 1000 2.5K.

I can't see that log on most of my machines because I don't have the Microtech software installed. What is the issue?

Looking at the text log it shows sT behing all of the injector output No.s & the map on RHS is RPMwot. Idling roughly obviously. The injector outputs range from 7 to 10 and because the wrong map is in use adjusting the idle map does nothing. I checked my staging is at 3000 rpm and 0psi I think. Have to check my computer when I'm home but the RPMcrs and RPMwot maps are set to off. Sorry I'm going by memory. Will post again when I get home with better atattchments.

Your water can't be 13/14 degrees with a running engine.

ST means that staged injection is on, and only the primaries are operating.

Those injector times are nuts, probably because the car is in warmup and it isn't tuned.

Also, get off of normal mode and go into Matrix mode. Normal mode is a carburetor.

The text shows the water at 44-48, it didn't cut and paste all that clear.
With the St, you are saying that it will turn to ms when the criteria are met and my secondaries come on.?
I did have a reasonable idle at around 3ms origonally, I thought that I must have altered one of the settings when I last looked through them. Doesn't matter what I set the idle screen to because it is using the rpmwot map not the idle map.
I will have a crack at matrix mode and see how it turns out. Will this change my running on rpmwot at all?

Yes, it will indicate MS when all injectors are operating and ST when only the primaries are operating. I believe this is mentioned in the manual because it is weird.

The ECU probably thinks you are at WOT becuse of the bridgeport pulsing. Switch to Matrix mode. Once you go Matrix mode, you will have a 3D table like all other ECUs and all the crap of RPMWOT, RPMCruise, etc. is ignored.

Ha, I see that now. "sT
=staged injection active (primary currently on)"
I had only remembered page 23 "The MicroTech Handset indicates when the secondary injector bank is active by displaying the letters "sT"
instead of "mS" in the OUTPUT display."
Kinda contradictory, but you've got one of these so I will take your word for it. Awesome about that matrix mapping. Been at work so haven't had a chance to try it yet.

Cheers Aaron.

Screen 19. Turn Pump1Stop and Pump2Stop to "Off". You will then be in TPS mode.

Full bridgeport...Even my small half bridge will only pull about 5" at 1000 RPM.

When your intake port is in constant overlap and always open to the exhaust port, at low RPM there isn't much opportunity to draw vacuum. But then set the idle to 1500RPM (where I have it set) and it then draws about 13".

All work and no play the last few weeks. I get four days off from tomorrow. I have a PS 1000 on the way, but will still see how far along I can get with the LT with the information that I have now.

Uhhhhh, had another go with the microtech with little success. Flagged it and hacked in the microtech. So far so good, no spark though. I had the x4 box in there, didn't realise but makes sense that the factory ignitor has been bypassed. Dose anyone know if the x4 is compatible with a haltech.
