knightsports ecu

[rx7ben]

Hi all im new to the club.
 
 I bought a  1993 rx7 Type R about5 weeks ago witch blow up the first night i had it. Since then ive had allmost evrything replaced by roetecnics. It has a knightsports ecu on it and i have the knightsports boost controler with it the thing is the car stinks of fuel when running, im shaw it must be runing really rich alltho it does have a straight threw exhaust. Allso the car doesnt feel as quick as i thought it would. Its not standard it has a Knightspiorts ecu and  intercooler, airfilter staight threw exhaust and lightend flywheel so i would of thought it would of felt quite quick. Could these thing be due to the ecu not set up propaley and needs ajusting or what about the boost could it be turned down to much.
 
any help would be great

If its a Knightsports unit you need to send it back to them with ful spec of the car so they can readjust it for you. If its just been imported then its set up to run a Japanese ron fuel which i higher than V Power over here.
 
Other than than you best bet is fitting a Apex\'i Power FC which would be i direct replacement. Also there are many more places in the UK that can Map a PFC so if you make more changes in the future it will be easier to re map

OK cheers for that info. As far as im awair it was imported about a year ago hope it doesnt need sending back. I s there not people in  the uk that can map a knightsports ecu

Knightsport run a "closed loop" set up. You need their software to open it. So in short no.

[rx7ben]

ok so sound like im better off starting from new. do you no the best place to pick up a Apex\'i Power FC from

Sounds like you might be running the engine in atm ?  If so, don\'t forget that Rotechniks turn the boost right down for the run-in.  If the Knightsport ECU doesn\'t take that into account, then that may be why it\'s over-fueling (if it is).  Maybe wait for the run-in to complete and the boost set back up, then retest?  (i know my car felt a bit quicker once i finished run-in)

Not saying your wrong by any means but roetecniks never told me that thay turn the boost down when rebuilding a engine  he never exsplained that when running threw the runin.

Allso my brother has a clasic shape impreza running 280bhp witch feels really fast really throws you back in your seat. how should my rx7 feel compaired to this. Im asking to try and get a idea of how fast my rx7 should feel.

Hmmm - he mentioned it to me, and like i say - mine certainly felt quicker after the post-runin service...

Also, you it sounds like you\'re on the standard twins, so even with the uprated intake and straight-through exhaust, your bros\' scooby is probably either equal power, or making a bit more than you.  

Lastly, a lot of the rotary power kicks in at the higher-revs, which you shouldn\'t be hitting on the run-in - when you\'re in the 1.5k-3.5k range, the car is (comparatively!) sluggish...

Note: all the above is just my own observations with my car, and bits that i have read on these forums- hopefully one of the more experienced folks on here will be able to confirm/correct as appropriate

It is on standars twins but i thought it being a Type R thay have 280bhp as standard. Ive run it in now so it will be going back to roetecnicks sometime next week and are shall have a chat with them

If it is 1993 it is 255bhp from factory. The types are just trim levels type r i think the lowest. Only the post 1999 had 280bhp.
Scoobs are geared low for quick accelaration they useless at maintaining high speeds as standard, but very quick at low speeds.
The car will be quicker at the end of the runin as the compression goes up. Depending on whever you had housing changed this could be 500 or 1000 miles ish.

If you need a PFC supplied then please let me know. We supply direct from Apex\'i and have a few units with commanders in stock.

[fil_auto]

apols for jumping in here but it seems the perfect opp!

What\'s a PFC and commander for a 95 type RB GONNA SET ONE BACK THESE DAYS?
aM THINKING THIS SHOULD BE ONE OF THE NEXT PURCHASES AFTER RUNNING HER FULLY IN ETC....

Then it\'s gotta be installed setup and mapped, right?!

TTFN pHIL.

ps: excuse the CAPS, only just reaised after typing the post..... #;o)

Hello RX7ben

Welcome to the club

Ditch the ECU and get your self the Apexi PFC As jm-garage says Apexi will be a direct replacement.  It will be the best mod you will ever spend your dosh on !!!!

If you need a really good map go and see Kerim at Powergains Motor Sport here in London (RX7 specialists).  Many of us here (on this site in London) use the above company.

I had a rebuild done by the above company and they have looked after my car for 2 years now. Rotechnics are very good but also very pricey; I am not sure how good they are at modifying the cars and mapping them

Power Gains Motor Sport will be much, much cheaper.  Legendary Jay Dee will map / tune your car

Well mapped twin turbo with decent mods will trash Type R – I have on more then one occasion..  (Running around 350BHP on 0.92 boost)

You should defo get a kick at around 3k revis and another at around 5k revs. The kicks are quite substantial so if you are not feeling that then something is wrong with your turbo set up / map

Regards,
Michaelb
