HULKSCOOBY Posted February 2, 2015 Posted February 2, 2015 Ok so ihave just bought a classic impreza wrx, I ws told it was running about 260bhp and full 3inch decat, apexi induction kit. I removed the panel to see what ecu it had in. The box said Z4 but i noticed a HKS fuel cut defended surely it wouldnt need this on the z4 ecu? anyway i can check if it is a z4 ecu or if its been mapped/chipped? cheers in advance Mike
quit Posted February 2, 2015 Posted February 2, 2015 Savage will know more mate ! Should have a daughter board
HULKSCOOBY Posted February 2, 2015 Author Posted February 2, 2015 Iam hoping it has a daughter board otherwise looks like il be splashing out on something mappable!
HULKSCOOBY Posted February 2, 2015 Author Posted February 2, 2015 I havent, only had a quick look under the panel and thought it was standard, i will whip it off after work tomorrow and take a look, will you be able to tell from photos?
savage bulldogs Posted February 2, 2015 Posted February 2, 2015 Z4 ecu was for a early wrx which had 260 hp standard . Some people do fit a fuel cut defender when using manual boost controllers to allow it to run more boost without hitting fuel cut . A esl daughter board could be fitted and would be easy to spot with the ecu "case" removed Looks a bit like this depending on version 1
HULKSCOOBY Posted February 2, 2015 Author Posted February 2, 2015 cheers for the help, doesnt appear to have a manual boost controller but will take a look tomorrow and see. If there is a daugher board there i think thats the closest il get to winning the lottery!
HULKSCOOBY Posted February 3, 2015 Author Posted February 3, 2015 Two quick photos i can get? Standard ecu?
savage bulldogs Posted February 4, 2015 Posted February 4, 2015 I would've said it's standard as the esl board is quite large and distinctive but subaru standard ecus normally have a letter and a number (6s , sa, z4 ..... ect) on the casing . Have you googled the info on the sticker ? It might be chipped or be a aftermarket ecu , although I've not heard of the funny tech factory before . Simtek Apexi Gems Esl Syvecs Are about the only mappable options I'm aware work on the early classics .
HULKSCOOBY Posted February 4, 2015 Author Posted February 4, 2015 The casing does have Z4 on the casing, there is a chip, however picture is not clear enough to read the writing on it. I am picking it up from my mechanics tomorrow so will take a closer look tomorrow. Should i run higher octane fuel, will it benifit the vehicl?
savage bulldogs Posted February 4, 2015 Posted February 4, 2015 Always run the high octane with a jdm ,unless it's been remapped for uk fuel, as their mapped from the factory to use hi octane . They're are "chips" which are a generic map with higher boost and more aggressive cam timing , like a "mines" ecu chip but imo you can't beat a bespoke remap
HULKSCOOBY Posted February 5, 2015 Author Posted February 5, 2015 Anyone seen this chip? Is it standard?
savage bulldogs Posted February 5, 2015 Posted February 5, 2015 I can't help there I'm afraid as I haven't seen the inside of a standard ecu , only esl'd ones and my current apexi .
hurrell942 Posted February 22, 2015 Posted February 22, 2015 Hi im a newbie just bought a 99 wrx few wks ago iv been driving it sensibly untill fri arvs after work .I start her and warmed her up then took of flat out in first gear just as I hit around 5000 rpm it choked big time so I backed off and pop it into 2nd gear I then proceeded to drive on slowly progresing through the gears it drove as norm until I tryed even in a higher gear to put my foot down a bit it would completely cut out again ??? I noticed savage bulldogs mention something about fuel cut out is this maybe whats going on ?? I love this car im !Removed! myself iv done some serious damage . Any suggestions appreciated untill I have her looked at
savage bulldogs Posted February 22, 2015 Posted February 22, 2015 Have you got a boost gauge if so what does it read at full chatt ? Any other mods fitted ?
hurrell942 Posted February 22, 2015 Posted February 22, 2015 Hi mate no no boost gauge only other mods I can see are a big fat exhaust system . Iv been driving it sensibly till I have a mech look at it and explain a few things about the boost untill I went and had a dumb brain moment and give it some curry :/ so tempting though .
hurrell942 Posted February 22, 2015 Posted February 22, 2015 There is a small gadget under the Stereo that has a little blue screen which is reading - 55 And fluxtuates to about -65 ?? Is this the gauge you speak of iv been trying to google what it is .the bloke I bought it from wasnt real helpful but I liked the car .
Steveuk260.Esq Posted February 23, 2015 Posted February 23, 2015 M ight be helpfull if you can manage to post a pic of it.
Steveuk260.Esq Posted February 23, 2015 Posted February 23, 2015 Like I thought its a turbo boost controller. meaning it bypasses ecu control it is not original part of manufacturing it has been added later. As it stands it could be set up wrongly that could be your issue.
hurrell942 Posted February 23, 2015 Posted February 23, 2015 Ah ok . Iv got it booked in tommorow hopefully I havent hurt the engine thankyou for your assistance.il post the verdict . Iv alot to learn about my suby but the part about it bypassing the ecu does'nt sound like a good thing to have ?? What are your thoughts on them ?
stants Posted February 23, 2015 Posted February 23, 2015 Sorted for you [emoji3] It will probably have a high/low setting I'd turn it right down until the garage looks at it just to be on the safe side 1
hurrell942 Posted March 3, 2015 Posted March 3, 2015 Hi again , just thought id give an update on where im at with my wrx problem as I just got the mechanics story . According to him hes replaced fuel filter and has a air flow meter on order which according to him is the reason for rexy wanting to completely cut out when giving it some love ? He's the expert lol , any ideas what kind of money il pay for an air flow meter I wont know until he orders one tommorow .a heads up might help soften the blow
stants Posted March 3, 2015 Posted March 3, 2015 Depends what colour label is on it some are 100 others are 300-400
