is there any one who could help me with answering questions about installing an E8 onto a gsxr600 for use in a FSAE car? i have alot of questions .

An e8 is overkill on a bike, will it be turbo, if not use the stock ecu and a power commander.

ikari899

well its for a FSAE car so its not going to have stock exhaust stock intake stock gearing stock any thing. and its going to be working though a single 20mm restricter. i know it can be done with a powercommander but i have an E8 sitting around so i would like to try that first because the PC3 is sooo limited compared to a E8.

crispeed

Use the E-8 so you can compensate for air box pressure. With that restrictor you have to fabricate a very nice trick manifold/airbox to acheive the power lost by the restrictor. With the E-8 tune in aph-n-mode(TPS) with pressure compensation(map). Plus if you're serious about racing then you can add the MXL dash to the picture which is also compatable with the E-8.

ikari899

yup i would love to but i need help with the settings on the E8 first

crispeed

Setting for what? Post some details of the setup.

Is there a cam angle sensor?

Does it run sequential injection stock?

I have a GSXR 1K wiring harness, and it uses the same amp seal connectors that the haltech does. It would be cool to install it using the factory harness by just re-pinning the connectors.

ikari899

yup there is a cam angle sensor and yes it does run sequential injection stock. what doesnt nowadays.

wow is it really the same connectors ill have to go grab the stock 600 harness we have sitting around and check it out. that would be sweet. then we wouldnt have to buy another harness either...

well its a

ikari899

the set up?

gsxr 750 motor

8 tooth crank position sensor hall effect i believe

cam position sensor hall effect as well i think

custom intake manifold with a 160cc plenum

4 19lb/185cc injectors

tri Y header primaries are about 7" with the secondaries about 12". i cant remember exactly but i think those numbers are close.

then of course the 20mm restricter.

stock TPS, crank pos, cam pos, water/air temp sensors.

the stock coil on plug coils with what ever igniter i choose to use. taking recommendations on that one.

any thing else you need?

crispeed

The design of the cam sensor or actually the tooth or lobe count on the camshaft for the cam sensor.

ikari899

1 tooth

and the sensor looks very much like the crank position sensor on the FD and those are hall effect right?

reluctor

ikari899

aight what he said. and thank you VERY MUCH in advance for any help you can give. our team is looking forward to a real ecu this year and its my job to get them one working perfectly.

slo... marry me!!! holy crap the stock harness does fit!!! this is going to make my life so much easier i wont have to buy Haltech harnesses now and can just either repin or cut and solder the stock ones... thanks alot man!!

My vote is for re-pin, get a good set of jeweler screwdrivers and have at it.....


If pulling all cylinders through a restriction, I think you would have some gain from pulling the butterfly's out of the TBs and going to a single larger TB before the restrictor. This should allow you to run load sensing off the stock map (it should stabalise the vacuum pulses enough).

ikari899

here one sec so you can see what we are doing again this year.

intake manifold:



which has this restricter/TB attached to the end of it:



that goes in this:



the rules mandate the intake be in this order:
TB
restricter
forced induction(if present)
manifold
engine

its actually rather hard to tune based solely off of map because of the restricter so the TPS becomes the main method of tunning for most teams. i plan to first get a good TPS map then switch to map so we have a back up in place.

crispeed

With restrictor setups the size of the plenum has to be adjusted to suit. Ever notice most restrictor setups using huge plenums. Some form of ram air is also very beneficial. You would be surprised what a difference a properly designed ram air system can make. Have seen some setups go positive in the intake pressure.
Boost in a NA application is always a good thing as long as you have the proper ecu and tuner to take advantage of it.

ikari899

yeah we find with bigger then 3" plenums we have surging issues and trouble tunning the car. and as far as ram air we never reach speeds of over 50mph so it would be very very hard to take advantage of that. and as far as turbos go... baby steps first, we will move up soon i hope.

it is a dedicated autox machine.

ikari899

so im pretty sure i cant wire the haltech directly to the stock gsxr coils so could any one suggest some very small single post ignitors?

oh and i just repined the stock harness. it is VERY VERY easy to repin one of those connectors. all it needs is a normal flat head. and you push the white bar out. then just yank the cables right out of the connector.i dont know if any one knew how to do it so i thought i should share...

slo

iTrader: (1)

I am pretty sure the GSXR ignition has its own separate igniter box (not run directly from the computer. The one on my GSXR 1K seems to, I have never seen the wiring diagram though)

The easy way to do it is wire 2 coils together off 2 ignitors, like 90% of stock bikes including I believe the gsxr.

ikari899

naw the gsxr ECU runs the coils directly. or at least the harness goes straight from the coils to the ECU. which leads me to assume that.

i just pulled apart the whole gsxr harness and made my own here it is almost done.


itll look better when its done i promise

i wired up a couple more pins today and wired in the serial connector, so all i have left is the coil power and outputs but i cant really do that till i get some ignitors.

oh and i do have a question. will the haltech ONLY work with its air and water temp sensors or can i configure it to work with the bike ones?

slo

iTrader: (1)

It will work with almost any sensors. The sensor the sensor config menu has the settings.

ikari899

ok cool thats what i assumed but i realized i had never looked

ikari899

aight to let me confirm the settings for the trigger setup then.

multitooth general
16 teeth

just called haltech and they verified those ^^^

reluctor mode for the trigger
hall effect for the home
rising edge trigger
rising edge home

yes/no?

ikari899

well i just found out the crank position sensor is a "variable reluctance" sensor. so reluctor or hall effect?

slo

iTrader: (1)

reluctor

a hall efect sensor trigger wheel will be magnetic, or have embeded magnets (flying magnets)

a reluctor sensor itself is magnetic with a ferrous trigger wheel (no magnets)

I would re-think hall effect as the home
