Class One Posted March 26, 2007 Share Posted March 26, 2007 Doug, have you got any dyno sheets of your car running at BPU? Not for the power, but because dyno's usually print the AFR's on the sheet at the same time. No haven't had it dyno'd since decatting Well, you use up a lot of fuel and lose a lot of power. You may cause some real long term problems due to overfuelling and the occasional ping. An injector may fail if you drive it hard because it's constantly locked open. Can't say I've heard of many of these problems occurring though -Ian Best I get something sorted there then. What would you recommend bearing in mind that I'm auto and don't have vast sums of money.

Silly question, you know Ian is going to say emanage, and rightly so for something like this... Link to comment Share on other sites More sharing options...

Innovative LC-1 or AEM AFR gauge and an EMB will be just the ticket...don't for get your fields harness too! Link to comment Share on other sites More sharing options...
Kranz Posted March 26, 2007 Share Posted March 26, 2007 Innovative LC-1 or AEM AFR gauge and an EMB will be just the ticket...don't for get your fields harness too! Just bought an LC-1 on fleabay....£100 inc sensor new Emanage blue is a good, low cost option. With these two you'll be able to put fuel in at the 4000 rpm transition point, and reduce fuel at the top end where overfuelling is killing power. Save fuel too You can log the LC-1 on the emanage as you drive, then pull over and look at the recording.... change the map a bit and try again. Nice easy tuning.

tDR Posted March 26, 2007 Share Posted March 26, 2007 I went for an LC-1 + MAP2 piggyback ECU + replica fields (which I've had to partially rewire ) harness + home made det cans combo. I see the MAP2 as a lower cost alternative to the EMU + it's billions of harnesses / MAP sensor, with some nice value added features like electronic boost control, launch control and dash switch switchable on the fly maps. I'm a bit of a guinea pig with this piggyback ECU though, but will post up my findings on it once I'm fully up and running / done my road mapping and have posted a 1/4 mile time. Cheers, Brian.

Ian C Posted March 26, 2007 Share Posted March 26, 2007 I remember reading up on the MAP2 ECU and my personal opinion is that the EMU is better than it in a lot of areas and worse in a couple. However for this level of tuning (BPU) the EMB is perfect, the MAP2 ECU would be ace. I always recommend the E-Manages, I think they are fantastic, and remember I bought one for my own car long before I started mapping other people's cars, so my bias is from personal use and not making £s. I must make that clear, and also that there are other E-Manage mappers out there, I absolutely do not pimp myself on here because it would be wholly inappropriate considering the ol' moderator thang going on. Do your homework and choose your weapon -Ian Link to comment Share on other sites More sharing options...
merckx Posted March 26, 2007 Share Posted March 26, 2007 you can iron out the problem with Emanage blue or similar. . That's good to hear. So what about fitting an Emanage to my VVTI BPU car to control the fueling . I know Ian C got it working on Alex's single VVTI. How easy would it be to set up on my car?

Do your homework and choose your weapon -Ian IMHO EMB is the best bang for buck piggy back out there at the moment, easy to get to grips with and does exactly what it says on the tin. Tuning on your personal test track is pretty straight forward, if you dont mind pulling a few 140+mph runs. I use an innovate lm-1 coupled with an Innovate Auxbox-3 to do a the datalogging (though the EMB has great datalogging features) then tranfer the data to a custom excel worksheet to configure the EM mapping, then its just fine tweaking after that. The MAP ECU2 Seems an Excellent choice especially with its list of features, though personally i have no experiance of it yet, but will be fitting one to a UK spec Single turbo - and this is were i think its a good option - with UK specs, mainly for the MAF elimination.

I really don't get that mentality that it's just for UK / US specs though. Why should it be... MAF->MAP2 is just one 0-5V signal to another just like OEM MAP->MAP2 MAP. Cheers, Brian.

Whitesupraboy2 Posted March 27, 2007 Share Posted March 27, 2007 I have an emanage in my BPU and I have a smooth curve as no2 comes on and good AFR's and a good RWHP. http://www.mkivsupra.net/vbb/attachment.php?attachmentid=50338&d=1169294967 http://www.mkivsupra.net/vbb/attachment.php?attachmentid=50339&d=1169294967 Link to comment Share on other sites More sharing options...

Brian i didnt say it was just for UK/US spec cars, what i said was i would use it on a UK spec before id use an EMB as you can loose the MAF...and we still havnt figured the cause of the EMB ignition problem on UK specs yet, its personal choice not a recommendation :-) Marty Link to comment Share on other sites More sharing options...
tDR Posted March 27, 2007 Share Posted March 27, 2007 I know Marty I didn't mean you personally, it's just you see posts along those lines a lot. I just mean there's no real technical restriction.. Cheers, Brian. Link to comment Share on other sites More sharing options...
tDR Posted March 27, 2007 Share Posted March 27, 2007 By the way, there's a 3-pin jumper (J3) inside the MAP2 ECU for igniter drive which is by default set to low. All the US Supras had to change that to high for ignition to work... I suspect igniter drive is something to do with the EMB ignition problems? Cheers, Brian.

bondango Posted March 27, 2007 Share Posted March 27, 2007 Brian, tried the different Igniter Driver settings but no joy. I've also yet to hear from anyone running a UK or USDM supra with the Emanage Ignition working. I know Mohd says it does, but ive yet to see evidence of this. The 7mgte tripped up with the ignition control of the EMB hooked up, turned out you needed to simulate an IGF signal to the ECU as the EMB corrupted it. Another system over looked is the MAFTpro, similar to the MAPecu2 in many repects. Marty Link to comment Share on other sites More sharing options...
Alex Posted March 27, 2007 Share Posted March 27, 2007 That's good to hear. So what about fitting an Emanage to my VVTI BPU car to control the fueling . I know Ian C got it working on Alex's single VVTI. How easy would it be to set up on my car? Yes we did get it working, and we know lots about the VVTi's quirks now I think an EMB is ok for BPU, but for the VVTi you really should go for the EMU. Why? Well, The antistall is better, the MAF deletion is better, the target AFR system is there too...etc etc...I had some issues with bigger injectors, that had it been available I'm convinced the EMU could have sorted out (restarting after leaving it for 10mins to 4hrs.) Go for th EMU and you've also future proofed yourself upto mid Single. Link to comment Share on other sites More sharing options...
