8v With Haltech & Tb's

[petert 550]

I've just finished fitting a Haltech E6X, with 45mm TB's to a warm 1.9L 8V. It hasn't been dynoed yet, but I'd have to say how amazing it is. Turn the key, even when cold, and it just sits there, rock steady, at 850 rpm. Some wouldn't like it, as its lost its rough idle but it's now smoooth as.... It's running on MAP sensor rather than TPS. Trigger comes from the std. reluctor and I've locked the distributor.

Sounds good! How much was the ECU? Do you have to press the throttle for a few seconds when cold and then idles perfectly or just turn the key and presto?

Looking forward to the dyno results

hello i use Haltech to and i have no problems ..

 

so when you need Help maybe i can help you..

 

get on the Dynorun nad make the system perfect..

 

regards MAGIC

 

when you need i have wreite a Program for 1,9l 8v with 45mm i can send you the file .. than you can try my programm .. i be sure that is better ..

Pete, what sort of spec is 'warm'?

 

Presume it is circa 150bhp... If so, why not use smaller TB's? Parts availability?

10:1, head job, Stage II cam. It's an interim solution. The owner is going to swap the 8V for a 16V eventually.

 

Magic,

I'd like to see your map, but unless it's got the same injectors (Bosch green 150) it won't run very well. I'll PM you for details.

Details (costs/mods) please Peter, that is remarkably similar spec to my car so am very interested.

They're currently AUS$1250.

 

Even when cold, just reach through the window and hit the starter, no throttle.

That's brilliant, just like a modern car!

did you do the mapping yourself?

Think in the UK it's around £550, not sure if it includes VAT.

[petert 550]

yep, I've been mapping them for approx. 15 yrs. It has three maps which help cold starts:

Primer Map- a large one off injection when you hit the key, I use approx. 250ms

Post Start Map - a decaying % of fuel after in fires

Coolant Map - a regular % of fuel enrichment versus temperature

Feb,

 

There is a UK distributer listed on here:

Sounds good, be intweresting to see what power & torque it makes now.

Almost sounds like my car on MP3.1. (it still has an occasional flutter but doesn't stall).

Hi Rob,

Yes, saw aet turbos are the main UK dealer(?), i wonder who has experience mapping these in UK (apart from them).

It will be sometime before/If i decide to upgrade to 3D management but it's good to know

Let us know of the results petert.

What's ambient temp in OZ at the mo?

 

My own 8v on tb's & Eemrald can hit that sort of rpm from cold when it's around as cold as 10 degrees...Around Zero degrees, slightly lower rpm but still solid...

 

Emerald has all those fucntions but the decaying percentage is not adjustable...

around 20 deg. C

20 deg.C would definetly not have trouble hitting 850rpm for a cold start

Seems though that you don't have to touch the throttle at all from what petert says unlike Emerald and Omex where you need to stay on the throttle for the first 15-20 secs .

Could be either the mapper or the cold start functionality.

I don't need to either at those temps....Also where's the location of Pete's injectors? standard postion or further away? i.e in the bodies.

 

How cold does it get in Oz.....20 degrees is warm for us

Where I live it gets down to 3-5 deg. on winter mornings, 14-16 on a summer morning.

Hey guys, this car Peter put together was mine. Thanks to Peter we were able to get 125hp at the wheels even though the coil was breaking down. There is more in it with some ingitions mods.

 

The weekend after I ran it at a Hillclimb here in AUS and was able to come second outright from a field of 60 cars. The only car to beat me was a Lotus Exidge.

 

The torque of the motor is just amazing.

Nice one, me thinks Peter is a bit of a legend over there for pugs..

Peter, as i understand this 8V doesn't have a IACV fitted, is that correct? In your other post you mentioned that "fuel enrichment VS coolant temp" by itself is not enough to get a steady idle.

 

This map for the 8V on TBs has as you mentioned:

 

"three maps which help cold starts:

Primer Map- a large one off injection when you hit the key, I use approx. 250ms

Post Start Map - a decaying % of fuel after in fires

Coolant Map - a regular % of fuel enrichment versus temperature"

 

What is the "Primer Map" and where do you define these maps in the haltech software (i can't see them in Options->Idle speed control)

Where is the "Post Start Map" and what does the decaying of fuel depend on (time after firing i guess?)

 

As i understand these 3 maps are adequate without the need for an IACV to get a proper idle?

Do you think that a IACV would be necessary for a car with power steering to compensate for the load on the engine during idling?

 

Thanks a lot for your help so far and bearing with my questions

[feb 47]

EDIT: I realised that some models of TBs have a hole to fit IACV but was reading in a different post that even in TBs without it there is enough air going to the head even with the butterflies closed?

[petert 550]

No this 8V doesn't have, or need an idle valve. I was referring to the 16V with a standard inlet manifold.

 

The Primer map is in the "MAP" menu, "Fuel Priming Map". As I said, it's a once off squirt.

 

Post Start is also in the "MAP" menu, "Fuel- Post Start Enrichment Map". The default time is 60 sec. but you can change this value, Post Start Time, in the "Fuel Setup" from the "Setup" menu. Yes, it's the time an enrichment will occur after firing, but only for up to 120 sec. max.

 

Engines with TB's generally don't need an idle control valve, certainly not the 8V or 16V 1.9L.

Petert, nice to read what you've done! from your initial post am I reading it correct that you have reatained the complete standard ignition system, trigger from reluctor on the disi, locked dissi, standard coil and ignition module running stock rev counter? I'd like to run this on mine, is there any problems running initialy on ignition only on carbs with full fuel injection system, there would be no problems of damaging the outputs to the injectors on the ECU or can these be isolated on ignition only?
