anyone used hondata?

did try this a few months back, and although it worked, the resolution is just not there to use the MAP sensor alone and using the TPS had some very undesirable effects, (I know Hondata have released newer versions since then, so this may well have improved).

EFI although hard work to initially get the configuration right, is a way more flexible option, for starters, you can define what tables you want to use, how big/small they are, what interrelationship there is between them, etc etc etc. big learning curve, but worth it, and it costs nothing like the Motec stuff (and I think it's more flexible).

So they will work with P/S pump? are you sure about that? have you actually seen it done befor?

I just ask because I was told only the HEYWARDS WOULD WORK WITH THE p/s PUMP

The Civic type R/S etc, have electric power steering, so if you have hydraulic power steering it won't work with out mods, and the tuned length to fit under hood is very short (air horns), max throttle size 48m/m.
LHP

yes, 100%...

I have seen them fitted up with the integra PS pump, they are not even close.

Also, 48 is not the max, we have used 51mm, and can go bigger, but have not reached the limits of 48 yet (48 is a shit big TB, unless you shooting for over 300 *real* Bhp, they are not going to be streached).

Your talking about the 51m/m taper throttles, correct, which taper down to 45m/m at the flange to the manifold.
Most North American customers are asking for the largest throttles possible,as they are "dragracing", 52m/m and 54m/m, not roadrace or rally, and this is why I had to make up my own manifolds for these uses.
I'm only using straight bore throttles,48,50,52,54m/m.

yes and no, there are 51 taper's (as you say, down to 45) but there are also 51 straight. That said, I cannot belive that *anybody* is actually making sencible use of 50+ TB's, if you do the numbers, it just does not make sence...(unless we are talking 2.5L+ fully worked engines making 300+ *real* bhp)

Please note that although Jenvey make this manifold, it's not the std one they sell, it was done speciffically for Clockwise.

Like I said further up the thread, this one is designed for stock civic install, they are working on other solutions too.

never heard of efi, i did think hondata had released new software though

i presume this is a daily driver- any dynos?

is this efi ecu the one marketed by clockwise on their website

correct.

EFI are one of the leading manufactures to the trade, they provice OEM solutions for ECU's to many smaller manufactuers and also small projects for the larger ones. they are the std ECU for British Touring car, Honda UK use them for on-off development work, Lotus use them for their OEM ECU (S2 Elise including Toyota engined cars), etc etc.

the one I have is a version of their Euro-1 ECU, although note that they are application specific (as in you need to get the right Euro-1 for the Honda K20)

Clockwise have been working with EFI to intergrate this thoughly with the K20 including being able to be used in road going cars and still have full dashboard support etc.

Mine is in a Lotus Elise race car, and although it's technically road legal, it does not go on the road.

dyno wise, nothing to really show at the moment, we have been working on the intergration and setup at the moment. once this is thoughly tested, then we will start to work on the engine, there is quite a lot of work invoved in getting the firmware and configuration right before you even start to map an engine, and we are making sure this is 100% before trying to make zillions of horspower.

Alright i really hate to keep asking but I just want to make sure. These ITB's fit on a K series motor while using the hydrolic P/S pump? not the electric Civic pump?

Thanks

Sure the pump will fit, if you want to relocate it farther down on the engine, but not in stock location with stock pump mount/oil separater.

I have their ITB's on my race car at the moement.

some notes...

1) the induction path is 100% straight
2) they will fit with the std idler pulley OR power steering pump.
3) they will work with 45/48/51/etc throttle bodies (I have 48 straight ones)
4) they fit a std civic including carbon airbox without *any* mods to the car.
5) they fully support Honda IACV/brake booster/etc

they come complete with *everything* that is required to fit them, the injectors/etc.

does the carbon cover allow u to run a CAI? and does the carbon cover cover the entire itb's?

Actually, it's just a software change to do the K20A.

The Euro1 is a fantastic buy for any four cylinder app. It's easier to tell you what it can't do (which isn'y much). We've used them on Peugeot, Renault's and Honda (with both kinds of VTEC) with sensational results.

Oh, and of course, we use it on my favourite customers race car. :wow:

what are you on about??????

it fit's with the pump is the STANDARD possition, it's not moved one bit still bolts to the top of the tensioner and uses the same belt etc etc etc...

where do you get this stuff from??

not sure about that??

it's definitly different hardware than the Euro1 we used for the Rover K, they have different daughterboards etc., although the main board and cases are all the same

Sorry, I was thinking of the Clio Sport. You are right,it's a hardware change not just software (although it does use a dedicated descriptor and editor file).

So are these ITBs a straight through design? and also they only go up to what was it 51mm?
