200sx-Starlet-Jay Posted February 19, 2009 Share Posted February 19, 2009 ive got a HDI EBC-R and i also opted for the rocket arming switch to change from low and high boost. its just hit me tho, the JAM ecu i am going to be buying... will it hold 2 different maps if you like, one for low and one for high, or will i have to give each setting a few runs each time i change from low to high or visa versa?? cuz i want to be able at the flick of a switch get an extra 30-40 BHP, but not sure if it is safe to just turn it up high and boot it, if the ecu will not have the correct fueling map in place straight away... sorry if im not making sense im trying to explain the best i can!!cheers to anyone who can shed some light on the situation!Jay Quote Link to post Share on other sites
Pav Posted February 19, 2009 Share Posted February 19, 2009 The Ecu will most likely be mapped for a Ct9 at 1bar of boost but will work most effeciently for what ever boost it was mapped for.It will run less boost perfectly safe, but will run slightly richer on a lower boost setting, limiting power output. So in otherwords it be fine. :surrender:Just find out what the Jam was mapped for originally if you can, and get it on the rolling road to check the afrs and power output at certain boost levels.My old blitz ecu for instance was still running quite rich even at 1 bar epsecially higher up in the rev range.

RobSR Posted February 19, 2009 Share Posted February 19, 2009 its the same principle just like the standard ecu and turbo.. as in 0.4 in low, and 0.6 in high and you can change when you want... Quote Link to post Share on other sites
StarletRick Posted February 19, 2009 Share Posted February 19, 2009 id change the boost controller though. the hdi ones are probably the worst EBCs you can buy. Quote Link to post Share on other sites
stylophonic Posted February 19, 2009 Share Posted February 19, 2009 how can you say that?, ^^is that first hand experience or are you going on bad reviews? Quote Link to post Share on other sites
Glanza_cl Posted February 19, 2009 Share Posted February 19, 2009 nothing wrong with them good, simple bit's of kit...do exactly what there supposed to do hold a nice strong boost that's adjustable :surrender: Quote Link to post Share on other sites
200sx-Starlet-Jay Posted February 19, 2009 Author Share Posted February 19, 2009 cheers pav makes sense more now!rick.. ive heard they are good and so thort i would give them a try. but ure answer hasnt answered the question!anyone else????Jay Quote Link to post Share on other sites
StarletRick Posted February 19, 2009 Share Posted February 19, 2009 i wouldnt say it was poor, unless i had used one. they have TERRIBLE gain control. by terrible i mean, they dont do it at all. ie. pants.for the money, idrather spend a few extra quid and get a blitz/greddy unit.

200sx-Starlet-Jay Posted March 2, 2009 Author Share Posted March 2, 2009 safe, lets just turn a general question into a WHOS GOT THE BEST PARTS thread... if it aint gunna help dont open ya trap IMO Quote Link to post Share on other sites
StarletRick Posted March 2, 2009 Share Posted March 2, 2009 its not a "who has the best bits" dick swinging contest. its fact, HDI boost controllers are not very good, they dont hold boost very well or accuratly. i was only recommending what i would buy as i have had experience with the hdi the blitz and the greddy and was trying to steer you in the right direction. you dont have to listen to my advice you cocky little prick. but i will have the "i told you so" card waiting for when it overboosts without you realising and you lose your ringlands. so go enjoy your boost.

200sx-Starlet-Jay Posted March 3, 2009 Author Share Posted March 3, 2009 cocky little prick? what have i said thats cocky? right, as far as im aware when you post somthing say a question for example... you post it to get advice on the question in hand. i have brought the hdi out of my choice, i have had blitz before, was happy with it and im not saying its not worth the money, or which i would rather have. FACT is im buildin a turbo lump up, not buying a peice of equipment bit by bit... so this has cost me a fair amount already. i was originaly goin with a manual controller but was then sold on this. if you are sayin that you have had HDI gear, then surely you could shed some light on the actual question asked, instead of telling me what i have brought is not up to your standard, or im sure anyones standard as its so bad?from what i can see your just taking this futher as u dont like what ive brought... i said at the start it hasnt answered my question cuz it clearly hadnt. now IM being called a cocky little prick? just let it go mate, i have..

Sparky Posted March 3, 2009 Share Posted March 3, 2009 Back on the topic of Boost controllers.... are Blitz Street SBC's any good? Quote Link to post Share on other sites
Pav Posted March 3, 2009 Share Posted March 3, 2009 Like the one on Tgtt sparky? Expect its pretty good, blitz have always been known to make good ebcs, even the old ones.As for the original question, the hdi will do the job you want it to do mate. If you dont like it or are not impressed, sell it and buy something else. Its your decision what you think of it at the end of the day. Quote Link to post Share on other sites
StarletRick Posted March 3, 2009 Share Posted March 3, 2009 i have had experience with the HDI, the blitz and the greddy units. i still stand by the "sell it and get a better one" statement i made earlier. as i said before. the HDI ones dont have a proper gain control. so managing boost is never easy. if youre spending good money on a turbo motor, why skimp on one of the most important pieces of kit? i have used a Greddy profecB2 (on my starlet) and it was great, held boost perfectly and i was running more than your average levels of boost. the blitz item is also good, i have the DSBCR on my s15 and i know of other people who use it and its really bloody good, better than the greddy even. with this in mind. think about your options. is a potential engine rebuild worth the 50 quid youre saving by using the HDI?

Sparky Posted March 3, 2009 Share Posted March 3, 2009 Yea the one for sale on TGTT, might get that then Quote Link to post Share on other sites
StarletRick Posted March 3, 2009 Share Posted March 3, 2009 if you can afford it lewis, get the dsbc, the one with the big solenoid block. the single ones are good. but the dual ones are the tits, very precise controls. Quote Link to post Share on other sites
RobSR Posted March 3, 2009 Share Posted March 3, 2009 yup, the blitz dual solenoid ones are very good, set one up the other day...(SBC ID) has quite a few nice features and holds boost perfectly Quote Link to post Share on other sites
Sparky Posted March 3, 2009 Share Posted March 3, 2009 I would if I could find one, the single one has come up for sale so it will do for now Quote Link to post Share on other sites
RobSR Posted March 3, 2009 Share Posted March 3, 2009 ^ theres nothing wrong with the single s. ones, they can only run 1.5 bar tho, but you aint going to be going above that Quote Link to post Share on other sites
Sparky Posted March 3, 2009 Share Posted March 3, 2009 Not for a while no Quote Link to post Share on other sites
