Injector Duration problem at startup

I am using a Haltech E11 V2 on my 87 rx7 and im using one of the Hitmans base maps to break in the motor. The car starts fine when the injector duration is around 2-5 m/s but sometimes when I turn the key to the ign position and go online with the E11, it says that the injector duration is a 66m/s. This does not allow me to start the car because of the massive amount of fuel being put into the motor when cranking. I think it has something to do with the correction maps. Any ideas about what I should do so that the injector duration is never reading 66 m/s? Thanks.

First: READ THE MANUAL until you understand it. That means, read the manual until you understand it. Got it? Now, that won't solve all your problems but we'll all be talking the same language. Now that you've gone and read the manual until you understand it, you'll know which of the correction maps apply. The most important ones are the coolant temp correction, post start correction, and battery voltage correction maps. Also make sure that its reading all the input variables properly (e.g. MAP, throttle pos, RPM) etc. which I assume it is.

I don't have the E11 so I can't comment too much on it, but if you are asking about correction maps it would suggest to me that you are a bit confused about what each one does and that's NOT good when you are trying to tune. You need to know pretty much exactly how each is gonna behave so you know where to look for stuff. Its worth the few hours to thoroughly understand the system. Maybe even read it a third or fourth time IN the car as you go to each map and play with it a bit.

66 ms is ridiculously high though. My engine idles with about 1.8-2.1ms of injection timing and is very unhappy outside of that range. The corresponding AFR is about 12.3 on my wideband. I don't think all the correction maps together could jack 2.1ms to 66. I'd make sure its looking in the right area of the map (hit the home key as its cranking so you can "jump" it to the fuel bar its reading from. That may give you a clue as to why its going so ridiculously high.

Also remember there is a priming feature which is (on mine) about a 40ms initial direct injection to prime the engine during cranking. I think I need to turn mine up or down a bit 'cos I need to crank for like 5 sec before she catches. But its reliably so.

Anyway that should give you some hints at where to start.

You know what to do....

I've READ THE MANUAL, and btw, im not trying to tune my car myself thats why im asking this. If I even attempted to tune the car I think I would'nt have to post this question because I SHOULD know how to fix something as simple as the primer map and corrections using water and iat. But thanks anyway.

Ummmm.... you're asking a tuning related question because you aren't tuning it? I'm not sure what you mean. If you aren't tuning it then your tuner should be able to handle this just fine, as you so eloquently stated. If you mean that you are not doing a FINAL tune, but you are doing a start/idle/limp-around tune, then you actually are tuning it yourself, to a degree. In which case you do need to understand these things.

Now, I wasn't trying to be mean in the least (note the copious smiley faces - this indicates friendliness and a lack of intended offense in net-speak) but you *did* ask the question. So, I am trying to help you. Even if none of what I said helped you, then kindly refrain from being sour in your answer. As you yourself said, you should know how to fix this. Or at least have more of a clue than you do.

So we have established the following:

1. You either have nothing to do with tuning this car, whatsoever. In which case you should not be asking this question to us, but to your tuner. Or
2. You are tuning the car yourself, for the purposes of getting it to start and run enough to get to the dyno shop or whatever. In which case you definitely should understand these principles.

Either way, the answer to your question is technical, its largely dependent on the information you can derive about your setup and then apply that understanding to the tools (maps, etc) at your disposal. So we expect if you are setting up a haltech on a car, that you understand the basic principles by which one operates. So should we be speaking to your tuner (who -should- know already) or you?

The only thing I can think of is the 3D coolant map is ON.
If you look at the default 3D coolant map, it's jacked all the way MAX!
I tend to turn it off and switch it to 2D and adjust that.

HAHAHA, Digital Synthesis your no help here just get out of my thread.... Thanks RETED for some REAL HELP. Thats the kind of reply I was looking for. BTW, my car does run, but im using a map that has no corrections enabled like post start or coolant. It just takes a while to start thats why I would like to adjust this problem so that I can have easier startups. Thanks.

What Halwin version are you using?
I think you should be able to bring up the Data Pages | Corrections and check to see what the hell is adjusting your fuel maps?

Hey, I don't think you can use V1.3 with anything lower than firmware version 18 / 19?
Try stepping down to v1.24?

I believe they all do.
Even the lowly v1.09 could do it.
